2366d23573 arch: arm: stm32l4: Rework pinmux driver
STM32L4 pinmux handler is reworked to support future pinmux dts
generation.
Preliminary change is done to move pin configuration
informations in a {pin, conf} structure closer to dts fields
"pins" array is removed and information is transferred to
"pinconf" array

8e8d49a620 i2c: stm32: Cleanup how we enable the specific I2C driver
Right now we allow for the I2C subsystem to be built without any drivers
enabled that utilize it.  When we added support for the new STM32 I2C
driver we forced the I2C driver to be enabled if the I2C subsystem was
enabled.  While this makes a reasonable amount of sense, it breaks
current assumptions for various testcases that we need to cleanup.

257e22bf38 arm: nxp: mpu: Fix region descriptor 0 attributes
Clearing fields in the region descriptor attributes doesn't always have
the expected effect of revoking permissions. In the case of bus master
supervisor mode fields (MxSM), setting to zero actually enables read,
write, and execute access.

When we reworked handling of region descriptor 0, we inadvertently
enabled execution from RAM by clearing the MxSM fields and enabling the
descriptor. This caused samples/mpu_test run to throw a usage fault
instead of an MPU-triggered bus fault.

Fix this by setting all the MxSM fields to 2'b11, which gives supervisor
mode the same access as user mode.

bacbea6e21 arm: nxp: mpu: Rework handling of region descriptor 0
The NXP MPU requires special handling of region descriptor 0 to
guarantee that the debugger has access to the entire address space. It
does not allow writes from the core to affect the start or end
addresses, or the permissions associated with the debugger.

The original implementation of this driver attempted to work around
region descriptor 0, resulting in an off-by-1 error caught by Coverity.

Instead, define region descriptor 0 explicitly in the mpu_regions array,
and add some asserts to ensure that one doesn't try to change its start
or end addresses. This has an added benefit such that more permissions
can be enabled in region 0 if desired, whereas the previous
implementation always forced all writable permissions to be cleared.

d2e38decf0 arm: nxp: mpu: Return constant number of mpu regions
The original implementation of _get_num_regions() parsed the CESR[NRGD]
register field to determine the number of mpu region descriptors
implemented in hardware. There was a possible path in the code to return
zero, which would cause underflow later on in arm_core_mpu_configure().
Coverity complained despite an assert to catch this condition. Instead,
use a preprocessor macro from mcux that defines the number of mpu region
descriptors.

ae1a75b82e stack_sentinel: change cooperative check
One of the stack sentinel policies was to check the sentinel
any time a cooperative context switch is done (i.e, _Swap is
called).

This was done by adding a hook to _check_stack_sentinel in
every arch's __swap function.

This way is cleaner as we just have the hook in one inline
function rather than implemented in several different assembly
dialects.

The check upon interrupt is now made unconditionally rather
than checking if we are calling __swap, since the check now
is only called on cooperative _Swap(). The interrupt is always
serviced first.

The REGION bits (bit[3:0]) of MPU_RBAR register can specify the number
of the region to update if the VALID bit (bit[4]) is also set.

If the bit[3:0] of "region_addr" are not zero, might cause to update
unexpected region. This could happen since we might not declare stack
memory with specific alignment.

This patch will mask the bit[4:0] of "region_addr" to prevent updating

3989de7e3b kernel: fix short time-slice reset
The kernel tracks time slice usage with the _time_slice_elapsed global.
Every time the timer interrupt goes off and the timer driver calls
_nano_sys_clock_tick_announce() with the elapsed time, this is added to
_time_slice_elapsed. If it exceeds the total time slice, the thread is
moved to the back of the queue for that priority level and
_time_slice_elapsed is reset to zero.

In a non-tickless kernel, this is the only time _time_slice_elapsed is
reset.  If a thread uses up a partial time slice, and then cooperatively
switches to another thread, the next thread will inherit the remaining
time slice, causing it not to be able to run as long as it ought to.

There does exist code to properly reset the elapsed count, but it was
only compiled in a tickless kernel. Now it is built any time
CONFIG_TIMESLICING is enabled.

possible because the memory in the range 0x0818000 - 0x0FFFFFFF is

a9183cd518 flash: Rework and add flash device support for STM32L4x SoCs
The STM32L4x SoCs embeds a slightly different embedded flash controller
from the STM32F4x SoCs.

This particular controller has the following properties :
 - Up to 2 512KiB banks divided in 2KiB pages
 - Flash can be accessed in any sizes
 - Flash must be written in 64bit aligned 64bit double-words

The drivers/flash/flash_stm32f4x.c is refactored into a new common
drivers/flash/flash_stm32.c and drivers/flash/flash_stm32l4x.c is
created with the STM32L4x specific functions.

To ease the refactoring and keep common functions, the STM32L4x flash
headers are slightly modified to match the hardware reference naming
and solve compilation issues.

This patch adds the arm core MPU interface, a common way to access the
pu functionalities by the arm zephyr kernel.

The interface can be divided in two parts:
- a core part that will be implemented by the arm_core_mpu driver and
  used directly by the kernel
- a driver part that will be implemented by the mpu drivers and used by
  the arm_core_mpu driver

Clean-up the pinmux arrays as a preparatory work before adding more

This is achieved by the following two actions:
- Define the PAD macro to simplify the [x - 1] = y construct
- Reorder the declartions by bank / pin to make it easier to
  locate a pin among a high number of other pins, while minimizing the
  risk of conflict when two people add a new declaration for two
  different pins

d26cf2dc33 kernel: add k_thread_create() API
Unline k_thread_spawn(), the struct k_thread can live anywhere and not
in the thread's stack region. This will be useful for memory protection
scenarios where private kernel structures for a thread are not
accessible by that thread, or we want to allow the thread to use all the
stack space we gave it.

This requires a change to the internal _new_thread() API as we need to
provide a separate pointer for the k_thread.

By default, we still create internal threads with the k_thread in stack
memory. Forthcoming patches will change this, but we first need to make
it easier to define k_thread memory of variable size depending on
whether we need to store coprocessor state or not.

89ffd44dfb kernel: tickless: Add tickless kernel support
Adds event based scheduling logic to the kernel. Updates
management of timeouts, timers, idling etc. based on
time tracked at events rather than periodic ticks. Provides
interfaces for timers to announce and get next timer expiry
based on kernel scheduling decisions involving time slicing
of threads, timeouts and idling. Uses wall time units instead
of ticks in all scheduling activities.

The implementation involves changes in the following areas

1. Management of time in wall units like ms/us instead of ticks
The existing implementation already had an option to configure
number of ticks in a second. The new implementation builds on
top of that feature and provides option to set the size of the
scheduling granurality to mili seconds or micro seconds. This
allows most of the current implementation to be reused. Due to
this re-use and co-existence with tick based kernel, the names
of variables may contain the word "tick". However, in the
tickless kernel implementation, it represents the currently
configured time unit, which would be be mili seconds or
micro seconds. The APIs that take time as a parameter are not
impacted and they continue to pass time in mili seconds.

2. Timers would not be programmed in periodic mode
generating ticks. Instead they would be programmed in one
shot mode to generate events at the time the kernel scheduler
needs to gain control for its scheduling activities like
timers, timeouts, time slicing, idling etc.

3. The scheduler provides interfaces that the timer drivers
use to announce elapsed time and get the next time the scheduler
needs a timer event. It is possible that the scheduler may not
need another timer event, in which case the system would wait
for a non-timer event to wake it up if it is idling.

4. New APIs are defined to be implemented by timer drivers. Also
they need to handler timer events differently. These changes
have been done in the HPET timer driver. In future other timers
that support tickles kernel should implement these APIs as well.
These APIs are to re-program the timer, update and announce
elapsed time.

5. Philosopher and timer_api applications have been enabled to
test tickless kernel. Separate configuration files are created
which define the necessary CONFIG flags. Run these apps using
following command
make pristine && make BOARD=qemu_x86 CONF_FILE=prj_tickless.conf qemu

73abd32a7d kernel: expose struct k_thread implementation
Historically, space for struct k_thread was always carved out of the
thread's stack region. However, we want more control on where this data
will reside; in memory protection scenarios the stack may only be used
for actual stack data and nothing else.

On some platforms (particularly ARM), including kernel_arch_data.h from
the toplevel kernel.h exposes intractable circular dependency issues.
We create a new per-arch header "kernel_arch_thread.h" with very limited
scope; it only defines the three data structures necessary to instantiate
the arch-specific bits of a struct k_thread.

75caa2b084 arm: exception-assisted kernel panic/oops support
Put the reason code in r0 and make a SVC #2 call, which will be
propagated to _fatal_error_handler as an exception.

The _is_in_isr() implementation had to be tweaked a bit.  User-generated
SVC exception no longer just used for irq_offload(); just because we are
in it does not mean we are in interrupt context.  Instead, have the
irq_offload code set and clear the offload_routine global; it will be
non-NULL only if it's in use. Upcoming changes to support memory
protection (which will require system calls) will need this too.

We free up some small amount of ROM deleting _default_esf struct as it's
no longer needed.

cdb94d6425 kernel: add k_panic() and k_oops() APIs
Unlike assertions, these APIs are active at all times. The kernel will
treat these errors in the same way as fatal CPU exceptions. Ultimately,
the policy of what to do with these errors is implemented in
_SysFatalErrorHandler.

If the archtecture supports it, a real CPU exception can be triggered
which will provide a complete register dump and PC value when the
problem occurs. This will provide more helpful information than a fake
exception stack frame (_default_esf) passed to the arch-specific exception
handling code.

3b662555d1 arm: work around QEMU issue with _IsInIsr
The ICSR RETTOBASE bit is improperly implemented in QEMU (the polarity
is flipped) and the fix for it has not yet made it into a QEMU release,
although it is present in upstream master branch.

The symptom is that if we are not in thread mode, the system always
believes were are in a nested exception state, causing _IsInIsr() to
always return true.

Skip the nested exception check if we are building for QEMU.

This is a workaround until SDK-54 is resolved.

e09a04f068 arm: fix exception handling
For exceptions where we are just going to abort the current thread, we
need to exit handler mode properly so that PendSV can run and perform a
context switch. For ARM architecture this means that the fatal error
handling code path can indeed return if we were 1) in handler mode and
2) only wish to abort the current thread.

Fixes a very long-standing bug where a thread that generates an
exception, and should only abort the thread, instead takes down the
entire system.

to define the sized types in a consistent manor across all the

and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include

types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some

9b12803bf7 cc3200: Resolve DTS fixup.
As part of the transition to Device Tree, a temporary
HAS_DTS configuration variable, and a .fixup file per board
with symbol aliases were added.

This patch removes the cc32xx related fixup file
definitions, except for those used additionally outside
the cc32xx drivers.

Since cc32xx has DTS files, and since HAS_DTS will always be true,
it also removes the 'if !HAS_DTS' blocks from the cc32xx Kconfig
files.

632a07d987 gpio: stm32: Use atomic set/reset in stm32_gpio_set()
The current implementation of stm32_gpio_set() uses the GPIO output data
register to change the state of individual GPIOs. The generated
assembler needs at least 3 instructions: load / modify / store.

This opens a small race window, for example if a thread and an
interrupt both try to change the state of the same GPIO bank.

Use the GPIO bit set/reset register to perform the atomic change without
locking.

This also has the benefit of a more optimised implementation, which can
be useful for GPIO-intensive work. Compare the new version:

bf2d34ba30 arm: cortex-m: allow configurable ROM offset
Currently, ARM Cortex-M image ROMs are linked starting at the flash
device's base address (CONFIG_FLASH_BASE_ADDRESS). This prevents XIP
Zephyr applications from being linked to run from elsewhere on the
flash device. Linking Zephyr applications to run from elsewhere can be
necessary when running under a bootloader (i.e., booting into a Zephyr
application from a bootloader, not using Zephyr as a bootloader).

To enable this use case, add a new config option: FLASH_LOAD_OFFSET.
This option directs the linker to treat ROM as if it started that many
bytes from the base of flash on Cortex-M targets. The option defaults
to zero to preserve backwards compatibility.

This patch adds support for using device tree configuration files for
configuring ARM platforms.

In this patch, only the FLASH_SIZE, SRAM_SIZE, NUM_IRQS, and
NUM_IRQ_PRIO_BITS were removed from the Kconfig options.  A minimal set
of options were removed so that it would be easier to work through the
plumbing of the build system.

It should be noted that the host system must provide access to the
device tree compiler (DTC).  The DTC can usually be installed on host
systems through distribution packages or by downloading and compiling
from https://git.kernel.org/pub/scm/utils/dtc/dtc.git

This patch also requires the Python yaml package.

e290006144 serial: Introduce new mcux lpuart shim driver
Adds a shim layer around the mcux lpuart driver to adapt it to the Zephyr
serial interface.

NXP has multiple uart hardware blocks that implement different features
and have different register maps. The k64 has a uart block called
'uart', while the kw41 has a uart block called 'lpuart' (low power
uart). The MCUXpresso SDK provides separate drivers for each type of
uart block but with similar software interfaces. As a result, there are
also separate shim drivers in Zephyr. There is a 1:1:1 relationship
between hardware block, mcux driver, and mcux shim driver.

Because we now have two mcux shim drivers for the uart interface, a new
naming convention is created:

	<interface>_mcux_<hw block>

Where <interface> is the name of the Zephyr interface, in this case
'uart'. This convention is not new.

<hw block> is the name of the NXP hardware block, in this case 'lpuart'.
This is the new part, and distinguishes different hardware blocks
for the same interface.

cd8fd42de9 arm: soc: Add SoC series for ARM's Cortex-M Prototyping System (MPS2)
ARM's Cortex-M Prototyping System (or MPS2) [1] is a board containing
devices such as RAM, ethernet and display, and at its heart there is an
FPGA which can be programmed with various 'SoCs' which implement the
CPU, SRAM, UARTs, SPI, DMA, etc. There are also software simulations of
systems based on this hardware which are part of ARM's Fixed Virtual
Platforms (FVPs).

All of the above could be regarded SoCs in the same series so we will
treat them as such in Zephyr.

In this initial patch we add SoC support for the public FPGA image
which implements a Cortex-M3 CPU, and includes definitions to support
use of the UARTs on this.

ARM's documentation for MPS2 images are titled 'Application Note ANnnn'
where the number nnn is different for each 'SoC'. E.g. Application Note
AN385 is for "ARM Cortex-M3 SMM on V2M-MPS2" [2]. The files ARM supply
for programming the board firmware also make extensive use of the ANnnn
nomenclature, so we will use this for the SoC name in Zephyr. E.g. the
Cortex-M3 SoC will be called 'mps2_an385'. Note, it is not possible to
use the CPU type (e.g. M3) for the name as there are multiple FPGA
images for some CPU types (e.g. there are three Cortex M7 images
with differing FPU and MPU support).

9bc293c827 cc3200: Use peripheral driver library functions from ROM
Previously, CC3200 drivers had two options to use the peripheral
driver library APIs:
1) Build driverlib SDK files in Zephyr, in ext/hal/ti/cc3200/*
2) Link directly with the driverlib.a, from an externally installed
   TI CC3200 SDK.

A new option is added to replace option 2), and is now the default:
3) Use the driverlib functions already provided in ROM.

This enables a savings in code size, which will depend on the
types of device drivers configured and the number of SDK
APIs actually used.

A rom_report build of the shell sample application showed
a savings of about 2kb in code space using this new config option.

e2d3cc4b81 arm: Restructure ARM cpu related preprocessor conditionals.
The ARM code base provides for three mutually exclusive ARM
architecture related conditional compilation choices.  M0_M0PLUS,
M3_M4 and M7.  Throughout the code base we have conditional
compilation gated around these three choices.  Adjust the form of this
conditional compilation to adopt a uniform structure.  The uniform
structure always selects code based on the definition of an
appropriate config option rather the the absence of a definition.

Removing the extensive use of #else ensures that when support for
other ARM architecture versions is added we get hard compilation
failures rather than attempting to compile inappropriate code for the
added architecture with unexpected runtime consequences.

Adopting this uniform structure makes it straight forward to replace
the adhoc CPU_CORTEX_M3_M4 and CPU_CORTEX_M0_M0PLUS configuration
variables with ones that directly represent the actual underlying ARM
architectures we provide support for.  This change also paves the way
for folding adhoc conditional compilation related to CPU_CORTEX_M7
directly in support for ARMv7-M.

This change is mechanical in nature involving two transforms:

1)

  #if !defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  ...

is transformed to:

  #if defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  #elif defined(CONFIG_CPU_CORTEX_M3_M4) || defined(CONFIG_CPU_CORTEX_M7)
  ...

2)

  #if defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  ...
  #else
  ...
  #endif

is transformed to:

  #if defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  ...
  #elif defined(CONFIG_CPU_CORTEX_M3_M4) || defined(CONFIG_CPU_CORTEX_M7)
  ...
  #else
  #error Unknown ARM architecture

168695c7ef kernel/arch: inspect prio/sched_locked together for preemptibility
These two fields in the thread structure control the preemptibility of a
thread.

sched_locked is decremented when the scheduler gets locked, which means
that the scheduler is locked for values 0xff to 0x01, since it can be
locked recursively. A thread is coop if its priority is negative, thus
if the prio field value is 0x80 to 0xff when looked at as an unsigned
value.

By putting them end-to-end, this means that a thread is non-preemptible
if the bundled value is greater than or equal to 0x0080. This is the
only thing the interrupt exit code has to check to decide to try a
reschedule or not.

f955476559 kernel/arch: optimize memory use of some thread fields
Some thread fields were 32-bit wide, when they are not even close to
using that full range of values. They are instead changed to 8-bit fields.

- prio can fit in one byte, limiting the priorities range to -128 to 127

- recursive scheduler locking can be limited to 255; a rollover results
  most probably from a logic error

- flags are split into execution flags and thread states; 8 bits is
  enough for each of them currently, with at worst two states and four
  flags to spare (on x86, on other archs, there are six flags to spare)

Doing this saves 8 bytes per stack. It also sets up an incoming
enhancement when checking if the current thread is preemptible on
interrupt exit.

8e4a534ea1 kernel: enable and optimize coop-only configurations
Some kernel operations, like scheduler locking can be optmized out,
since coop threads lock the scheduler by their very nature. Also, the
interrupt exit path for all architecture does not have to do any
rescheduling, again by the nature of non-preemptible threads.

c3a2bbba16 kernel: add k_cpu_idle/k_cpu_atomic_idle()
nano_cpu_idle/nano_cpu_atomic_idle were not ported to the unified
kernel, and only the old APIs were available. There was no real impact
since, in the unified kernel, only the idle thread should really be
doing power management. However, with a single-threaded kernel, these
functions can be useful again.

The kernel internals now make use of these APIs instead of the legacy
ones.

88b3691415 kernel/arch: enhance the "ready thread" cache
The way the ready thread cache was implemented caused it to not always
be "hot", i.e. there could be some misses, which happened when the
cached thread was taken out of the ready queue. When that happened, it
was not replaced immediately, since doing so could mean that the
replacement might not run because the flow could be interrupted and
another thread could take its place. This was the more conservative
approach that insured that moving a thread to the cache would never be
wasted.

However, this caused two problems:

1. The cache could not be refilled until another thread context-switched
in, since there was no thread in the cache to compare priorities
against.

2. Interrupt exit code would always have to call into C to find what
thread to run when the current thread was not coop and did not have the
scheduler locked. Furthermore, it was possible for this code path to
encounter a cold cache and then it had to find out what thread to run
the long way.

To fix this, filling the cache is now more aggressive, i.e. the next
thread to put in the cache is found even in the case the current cached
thread is context-switched out. This ensures the interrupt exit code is
much faster on the slow path. In addition, since finding the next thread
to run is now always "get it from the cache", which is a simple fetch
from memory (_kernel.ready_q.cache), there is no need to call the more
complex C code.

On the ARM FRDM K64F board, this improvement is seen:

Before:

1- Measure time to switch from ISR back to interrupted task

   switching time is 215 tcs = 1791 nsec

2- Measure time from ISR to executing a different task (rescheduled)

   switch time is 315 tcs = 2625 nsec

After:

1- Measure time to switch from ISR back to interrupted task

   switching time is 130 tcs = 1083 nsec

2- Measure time from ISR to executing a different task (rescheduled)

   switch time is 225 tcs = 1875 nsec

These are the most dramatic improvements, but most of the numbers
generated by the latency_measure test are improved.

Fixes ZEP-1401.

7f4c294e5c arm: use interrupt stack during early init
The ARM Cortex-M early boot was using a custom stack at the end of the
SRAM instead of the interrupt stack. This works as long as no static
data that needs a known initial value occupies that stack space. This
has probably not been an issue because the .noinit section is at the
very end of the image, but it was still wrong to use that region of
memory for that initial stack.

To be able to use the interrupt stack during early boot, the stack has
to be released before an interrupt can happen. Since ARM Cortex-M uses
PendSV as a very low priority exception for context switching, if a
device driver installs and enables an interrupt during the PRE_KERNEL
initialization points, an interrupt could take precedence over PendSV
while the initial dummy thread has not yet been context switched of and
thus released the interrupt stack. To address this, rather than using
_Swap() and thus triggering PendSV, the initialization logic switches to
the main stack and branches to _main() directly instead.

32698293c8 kernel/arm: fix race condition when setting _Swap() return value
There was a possible race condition when setting the return value of a
thread that is pending, from an ISR.

A kernel function causes a thread to pend, with the following series of
steps:

- disable interrupts
- move current thread to wait_q
- call _Swap

Depending if running on M3/4 or M0+, _Swap will either issue a svc #0,
or pend PendSV directly. The same problem exists in both cases.

M3/4:
__svc will:
- enable interrupts
- trigger __pendsv

M0+:
_Swap() will enable interrupts.

__pendsv will:
- save register context including PSP into the thread struct

If an interrupt occurs between interrupts being enabled them and
__pendsv saving PSP, and the ISR sets the pending thread's return value,
this will happen:

- sees the thread in a wait_q
- removes it
- makes it ready
- calls _set_thread_return_value
- _set_thread_return_value looks at the thread's saved PSP to poke
  the value

In this scenario, PSP hasn't yet been updated by __pendsv so it's a
stale value from the previous context switch, resulting in unpredictable
word on the stack getting set to the return value.

There is no way to fix this issue and still have the return value being
delivered directly in the pending thread's exception stack frame, in the
M0+ case. There will always be a window between the unlocking of
interrupts and PendSV being handled. On M3/4, it could be possible with
the mix of SVC and PendSV, since the exception stack frame is created in
the __svc handler. However, because we want to keep the two
implementations as close as possible, and there were talks of moving
M3/4 to using PendSV only, to save an exception, the approach taken
solves both cases.

The approach taken is similar to the ARC and Nios2 ports, where
there is a field in the thread structure that holds the return value.
_Swap() then loads r0/a1 with that value just before returning.

Fixes ZEP-1289.

ignoring the fact that _is_next_thread_current() updates the next thread
cache when fetching the next thread.

f6ca7de09c kernel/arch: consolidate tTCS and TNANO definitions
There was a lot of duplication between architectures for the definition
of threads and the "nanokernel" guts. These have been consolidated.

Now, a common file kernel/unified/include/kernel_structs.h holds the
common definitions. Architectures provide two files to complement it:
kernel_arch_data.h and kernel_arch_func.h. The first one contains at
least the struct _thread_arch and struct _kernel_arch data structures,
as well as the struct _callee_saved and struct _caller_saved register
layouts. The second file contains anything that needs what is provided
by the common stuff in kernel_structs.h. Those two files are only meant
to be included in kernel_structs.h in very specific locations.

The thread data structure has been separated into three major parts:
common struct _thread_base and struct k_thread, and arch-specific struct
_thread_arch. The first and third ones are included in the second.

The struct s_NANO data structure has been split into two: common struct
_kernel and arch-specific struct _kernel_arch. The latter is included in
the former.

Offsets files have also changed: nano_offsets.h has been renamed
kernel_offsets.h and is still included by the arch-specific offsets.c.
Also, since the thread and kernel data structures are now made of
sub-structures, offsets have to be added to make up the full offset.
Some of these additions have been consolidated in shorter symbols,
available from kernel/unified/include/offsets_short.h, which includes an
arch-specific offsets_arch_short.h. Most of the code include
offsets_short.h now instead of offsets.h.

Since the nRF5x Product Specifications do not provide a

b4b108de4d unified: rename sched.h to ksched.h
Build breaks when enabling CONFIG_NEWLIB_LIBC because it has its own

This is a bad symptom of a greater issue: the build system passes many
'-I<path>' options to the compiler, and that allows including header
files by simply specifying their names (when located somewhere else than
<zephyr>/include/) and can cause clashes when several files in different
locations have the same name, like in this case.

35497d6c5e unified: cache the next thread to run
When adding a thread to the ready queue, it is often known at that time
if the thread added will be the next one to run or not. So, instead of
simply updating the ready queues and the bitmask, also cache what that
thread is, so that when the scheduler is invoked, it can simply fetch it
from there. This is only done if there is a thread in the cache, since
the way the cache is updated is by comparing the priorities of the
thread being added and the cached thread.

When a thread is removed from the ready queue, if it is currently the
cached thread, it is also removed from the cache. The cache is not
updated at this time, since this would be a preemptive fetching that
could be overriden before the newly cached thread would even be
scheduled in.

Finally, when a thread is scheduled in, it now becomes the cached thread
since the fact that it is running means that by definition it was the
next one to run.

Doing this can speed up considerably some context switch times,
especially when a thread is preempted by an interrupt and the same
thread is scheduled when the interrupt exits.

fc59e5b584 unified/arm: fix saving of registers in __pendsv()
The unified kernel calls a function (_get_next_ready_thread) to fetch
the next thread to run: it thus must save caller-saved registers that
are expected to hold a value before calling such function.

The callee-saved registers are available after saving them in the
outgoing thread's stack, so use some of those instead to reduce the
number of registers to save before calling _get_next_ready_thread. Also,
save caller-saved registers in callee-saved registers instead of on the
stack to reduce memory accesses.

This issue did not show up previously, probably because
_get_next_ready_thread did not use the regsiters that had to be saved,
but an upcoming optimization to that function stomps on them.

3cf3778d31 unified/arm: add unified kernel support for ARM arch
The ARM architecture port is fitted with support for the unified kernel,
namely:

- the interrupt/exception exit code now pends PendSV if the current
  thread is not a coop thread and if the scheduler is not locked

- fiber_abort is replaced by k_thread_abort(), which takes a thread ID
  as a parameter (i.e. does not only operate on the current thread)

- the _nanokernel.flags cache of _current.flags is not used anymore
  (could be a source of bugs) and is not needed in the scheduling algo

- there is no 'task' field in the _nanokernel anymore: PendSV not calls
  _get_next_ready_thread instead

- the _nanokernel.fiber field is replaced by a more sophisticated
  ready_q, based on the microkernel's priority-bitmap-based one

- thread initialization initializes new fields in the tcs, and does not
  initialize obsolete ones

- nano_private includes nano_internal.h from the unified directory

- The FIBER, TASK and PREEMPTIBLE flags do not exist anymore: the thread
  priority drives the behaviour

- the tcs uses a dlist for queuing in both ready and wait queues instead
  of a custom singly-linked list

- other new fields in the tcs include a schedule-lock count, a
  back-pointer to init data (when the task is static) and a pointer to
  swap data, needed when a thread pending on _Swap() must be passed more
  then just one value (e.g. k_stack_pop() needs an error code and data)

- the 'fiber' and 'task' fields of _nanokernel are replaced with an O(1)
  ready queue (taken from the microkernel)

- fiberRtnValueSet() is aliased to _set_thread_return_value since it
  also operates on preempt threads now

- _set_thread_return_value_with_data() sets the swap_data field in
  addition to a return value from _Swap()

- convenience aliases are created for shorter names:

  - _current is defined as _nanokernel.current
  - _ready_q is defined as _nanokernel.ready_q

- _Swap() sets the threads's return code to -EAGAIN before swapping out
  to prevent timeouts to have to set it (solves hard issues in some
  kernel objects).

67132c8689 nxp_kinetis: Add Kconfig options to configure clocks
Many Kinetis SoCs contain an Oscillator (OSC) module and a Multipurpose
Clock Generator (MCG) module to configure clocks. Adding options to
configure these modules for PLL operation with different external
oscillator frequencies, which can vary across boards. More options may
be added later to support other clocking modes such as FLL.

9f628943a8 toolchain: Remove vestigial COFF assembler symbol mangling support
The toolchain headers included an abstraction for defining symbol
names in assembly context in the situation where we're using a
DOS-style assembler that automatically prepends an underscore to
symbol names.

We aren't.  Zephyr is an ELF platform.  None of our toolchains do
this.  Nothing sets the "TOOL_PREPENDS_UNDERSCORE" macro from within
the project, and it surely isn't an industry standard.  Yank it out.
Now we can write assembler labels in natural syntax, and a few other
things fall out to simplify too.

(NOTE: these headers contain assembly code and will fail checkpatch.
That is an expected false positive.)

FUNC_NO_FP used to disable the usual C preamble to update the

or less. It's debatable how useful the occasional use of
FUNC_NO_FP is in practice since it hinders debugging and in a

ded3070c1c nanokernel: tighten _is_thread_essential()
Of the 3 related functions;
  _thread_essential_set()
  _thread_essential_clear()
  _is_thread_essential()

The first two are parameter-less and always operate on
"_nanokernel.current". The last one takes a 'thread' parameter but will
operate on _nanokernel.current if the parameter is NULL. All calls to
_is_thread_essential() pass NULL!

This change makes the 3 functions consistent by removing the parameter
to the 3rd function. This should also be marginally more efficient,
though consistency was the motivation. This change corrects the doc
preamble to all 3 functions.

(These functions would probably be better as inlines. Also, the choice
of when to use wrappers seems a bit arbitrary. E.g. there's nothing
for setting/testing the "FIBER" flag.)

264c207f4f Bluetooth: Add custom "monitor" protocol logging over UART
With most boards there's no simple way to get access to the HCI
traffic. Simultaneously these boards only have one external UART for
the console. This patch introduces a protocol which combines both
normal logs and HCI logs over a single binary protocol sent over the
console UART.

The protocol is modeled based on the btsnoop/monitor protocols used by
BlueZ, and the first tool that's able to decode this is btmon from
BlueZ ("btmon --tty <tty>").

For platforms with two or more external UARTs it is still possible to
use CONFIG_UART_CONSOLE as long as the UART devices used are
different, however on platforms with a single external UART
UART_CONSOLE should be disabled if BLUETOOTH_DEBUG_MONITOR is enabled

546b8ade37 refactor common driver initialization priorities
Most of the SoC and board Kconfig use the same values for
driver initialization priorities. So refactor them, and
discard duplicate ones.

The shared IRQ init priority was changed so that the kernel
default init and device init priorities can be standardized
across all SoC/boards. Same goes for DesignWare SPI driver.

This also changes the UART_CONSOLE_PRIORITY and
IPM_CONSOLE_PRIORITY to UART_CONSOLE_INIT_PRIORITY and
IPM_CONSOLE_INIT_PRIORITY, to standardize across all drivers.

Note that this does not take away the ability to override
those values. This just provides reasonable defaults such
that there is virtually no need to override.

8df10d4584 kconfig: untangle ordering and dependencies
There are two major issues with the kconfig:

() Some of the config options have incorrect dependencies inside help
   under menuconfig. For example, CONFIG_GPIO depends on BOARD_GALILEO.

() Since the SoC and board specific kconfig files are parsed first,
   the help screen would say, for example, CONFIG_SPI is defined at
   arch/arm/soc/fsl_frdm_k64f/Kconfig. This is incorrect because
   the actual config is defined in drivers/spi/Kconfig.

These cause great confusion to users of menuconfig/xconfig.

To fix these, the SoC and board defaults are now to be parsed last.

Note that the position swapping of defaults in this patch is due to
the fact the the default parsed last will be used.

And, spi_test is broken due to the fact that it requires
CONFIG_SPI_INTEL_PORT_1, but never enables it anywhere. This is
bypassed for now.

3f5af00529 clock_control/stm32f10x: introduce driver for STM32F10x RCC
The patch adds a driver for STM32F10x series RCC (Reset and Clock
Control) subsystem.

The module is primarily responsible for setting up of MCU's clock
tree. In particular the driver sets up SYSCLK, PLL (with source
configuration), AHB prescaler, and APB1/APB2 prescalers. As part of this
functionality, the subsystem can enable/disable clock signal for
particular peripherals, thus reducing the power consumption of the MCU.

The driver implements clock control driver API. However, subsystem IDs
being HW specific are exposed in driver public header that must be
included by callers. The driver registers a single device using a common
name STM32_CLOCK_CONTROL_NAME. The device is initialized at
the PRIMARY level with priority 1. This allows the initialization to
take place right after SoC initialization routine.

The driver depends on selection of SOC_STM32F1X config option and is MCU
specific.

1c78f3d39b st_stm32/stm32f1: introduce STM32F1x SoC family
The patch introduces a new family of SoCs based on STMicroelectronics'
STM32 MCU line. The patch introduces a basic arch/arm/soc layout along
with configuration of 2 MCUs from STM32F1 series: STM32F103VE and
STM32F103RB.

The patch assumes that other MCUs from STM32 family will be included
under arch/arm/soc/st_stm32 tree, to achieve the following layout:

arch/
  arm/
    soc/
      st_stm32/
        stm32f0/
        stm32f1/
        stm32f2/
        ...
        stm32l0/

Most of the configuration within a single MCU family (ex. STM32F1) is
shared, however individual MCUs differ with respect to SRAM size, flash
size or the number of available peripherals. The patch assumes that per
MCU line Kconfig.soc.family file should introduce basic setup for given
series. This can be further tuned by per MCU files, with
Kconfig.soc.stm32f103rb and Kconfig.soc.stm32f103ve as examples.

Each family defines a configuration option, ex. CONFIG_STM32F10X, while
individual MCUs define a corresponding per MCU config options,
ex. CONFIG_STM32F103VE.

From the menuconfig perspective, the user is presented with a family
selection under General Platform Configuration/SoC Selection.  A
specific MCU model can be selected by accessing General Platform
Configuration/STM32F1x MCU Selection, with the default entry being
selected by the board configuration.

d151776e59 debug: thread monitor allow to access more thread information
The thread monitor allows to iterate over the thread context
structures for each existing thread (fiber/task) in the system.

Thread context structures do not expose thread entry information
directly. Although all the information can be scavenged from memory
stacks. Besides, accessing the information depends on the stack
implementation for each architecture.

By extending the tcs we allow a direct access to the thread
entry point and its parameters, only when thread monitor is
enabled.

It also allows a task to access its kernel task structure

This reverts commit 3f6884902b.

This commit does not work as intended: the part in arch/arm/Makefile
gets ignored and -mcpu=cortex-m3/4 does not get passed to gcc. It seems
that the zephyr toolchain does not care, but the vxworks assembler
chokes if it is missing, and thinks the CPU does not support thumb ISA

995a9ba72a arm: K64 SPI module driver
Support for Freescale/NXP K64 SPI modules, limited to:

- Master mode
- A single active set of clock and transfer attributes (CTAR0), which
includes non-adjustable delay parameters
- Tx FIFO fill and Rx FIFO drain interrupt handling
- Standard, continuous select and continuous SCK SPI transfer formats

Also, divide-by-zero code generation in this driver is prevented.
The 'volatile' attribute is added to some of the variables in the baud
rate and delay calculation functions of the K64 SPI driver in order to
prevent bad code generation by gcc toolchains for ARM seen when an
optimization setting above -O0 is used.
Specifically, a register is loaded with the constant 0 and is used as
the divisor in a following divide instruction, resulting in a
divide-by-zero exception.
This issue has been seen with gcc versions 4.8.1 (the VxWorks toolchain)
and 5.2.0 (the Zephyr SDK toolchain).

52b499fd1f arm: Freescale K64/FRDM-K64F Pinmux support
K64 pinmux support is created as a normal driver.

As opposed to the Galileo board, the pin configuration options are
defined by the MCU and are not board-specific.  Separate
platform/board-specific configuration code uses the pinmux driver for
the default pin settings. For FRDM-K64F, only the Arduino pins (22 of a
possible 160) are set up.

Some of the I/O pins routed to the Arduino header are also configured as
JTAG/SWD signals by default and are used by the OpenSDAv2 debug
interface.  Therefore, a PRESERVE_JTAG_IO_PINS config option was created
for the FRDM-K64 platform to prevent the default pin settings from
re-configuring these pins.

The K64 MCU separates pin configuration and control, implemented in the
pinmux driver, from GPIO.  This results in some cross referencing
between the K64 GPIO driver and the K64 pinmux driver due to the
dependencies of one on the other.

This pinmux driver also uses the expanded pinmux function/mode parameter
size to describe pin configuration options with bit fields for the K64,
including up to 8 pin functions, plus interrupt, pullup/down, drive
strength, open-drain and slew rate.

The following GCC warnings in the K64 pinmux driver are prevented when not
compiling with 'no-optimization' (-O0):

warning: 'gpio_dev' may be used uninitialized in this function
[-Wmaybe-uninitialized]

e643cede3a uart: add ISR callback mechanism for UART drivers
The peripherals utilizing UART were required to register their own
ISR rountines. This means that all those peripherals drivers need
to know which IRQ line is attached to a UART controller, and all
the other config values required to register a ISR. This causes
scalibility issue as every board and peripherals have to define
those values.

Another reason for this patch is to support virtual serial ports.
Virtual serial ports do not have physical interrupt lines to
attach, and thus would not work.

This patch adds a simple callback mechanism, which calls a function
when UART interrupts are triggered. The low level plumbing still needs
to be done by the peripheral drivers, as these drivers may need to
access low level capability of UART to function correctly. This simply
moves the interrupt setup into the UART drivers themselves. By doing
this, the peripheral drivers do not need to know all the config values
to properly setup the interrupts and attaching the ISR. One drawback
is that this adds to the interrupt latency.

Note that this patch breaks backward compatibility in terms of
setting up interrupt for UART controller. How to use UART is still
the same.

This also addresses the following issues:

() UART driver for Atmel SAM3 currently does not support interrupts.
   So remove the code from vector table. This will be updated when
   there is interrupt support for the driver.
() Corrected some config options for Stellaris UART driver.

This was tested with samples/shell on Arduino 101, and on QEMU
(Cortex-M3 and x86).

630280c464 build: fix issue with static interrupts on ARC/ARM
Static interrupts rely on a trick where the _sw_isr_table array
is declared with each element in a different .gnu.linkonce
section, initially pointing to the spurious IRQ handler.

When drivers or apps declare their own interrupts, they override
the element with their own containing the real ISR and parameter.

However, this only works if the initial declaration of the
_sw_isr_table array with the spurious handlers is linked last.
App-specific code was being linked later than the core code,
causing static interrupts declared in apps not to be installed
correctly.

If the _sw_isr_table is moved from SOC-specific code to core arch
code, interrupts configured under soc/ should still also work.

bd94d98255 arm: add connecting exceptions at runtime
Add sys_exc_connect() (and its x86-compatible alias nanoCpuExcConnect())
that allows connecting an exception handler at runtime.

The current implementation is a bit of a bastard, to avoid disturbing
the current implementation of the exception handlers. Instead of hooking
_exc_wrapper() in all vectors and adapting the exception handlers, the
current exception handlers are still hooked directly in the vectors.
When an exception is hooked at runtime, _exc_wrapper() gets installed in
the vector and the real handler gets inserted in _sw_exc_table; this
means that the scheme only works with non-XIP kernels.

This should be enhanced so that _exc_wrapper() is hooked in all vectors,
and that current exception handlers (for faults mostly) are reworked to
be inserted in the _sw_exc_table and wrapped in _exc_wrapper().

2858cbf829 idle: fix tasks waiting when NANO_TIMEOUTS is enabled
Fix an issue where, if a task is pending on a nano timeout, the duration
it wants to wait is not taken into account by the tickless idle code.
This could cause a system to wait forever, or to the limit of the timer
hardware (which is forever, for all intents and purposes).

This fix is to add one field in the nanokernel data structure for one
task to record the amount of ticks it will wait on a nano timeout. Only
one task has to be able to record this information, since, these waits
being looping busy waits, the task of highest priority is the only task
that can be actively waiting with a nano timeout. If a task of lower
priority was previously waiting, and a new task is now waiting, it means
that the wait of the original task has been interrupted, which will
cause said task to run the busy loop on the object again when it gets
scheduled, and the number of ticks it wants to wait has to be recomputed
and recorded again.

e55bf6cb0c arch/arm: define flash/SRAM base addresses per SoC
This removes the default flash and SRAM base addresses from the ARM core
Kconfig file. Each individual SoC/processors Kconfig has to define them.
This is in preparation to support Atmel SAM3 family processors as they
have different base addresses.

b43af743b7 Move compiler optimization to the SoC
Decisions on compiler optimizations were done on the architecture level,
this does not scale and some SoCs will have different optimization levels
or compiler options needed. Moving this to the SoC makes it easy to optimize
differently when using the same CPU which we use to set the right optimization
now on the architecture level.

For IAMCU platforms, use the right architecture and tuning.

d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

8a3273aeb6 arm/fsl_frdm_k64f: serial/uart_k20: rework UART clock gating
The code to poke the system integration module to disable clock gating
for UARTs only works for UART0-3 since all the bits are in the same
register. However, clocks for UART4 and UART5 are controlled by
another register. This means that we have been writing to the wrong
bit for enabling UART4.

This patch fixes this issue, and moves the clock gating clock into
board initialization. The incorrect code has also been removed to
prevent accidental mis-use. The dev_data struct is no longer needed
for uart_k20, so that is removed as well.

Use CONFIG_PLATFORM to only build the selected platform. This
will enable support for drop-in platforms. Makefile will not need
to be changed for every new platforms.

c3a7fd2844 arm: use wildcards for kconfig
Move platform related data and definition to the platform
directory and include it using:

arch/<arch>/platforms/*/Kconfig.platform

This way we will able to add a platform as a directory of
content without the need to change and Kconfig files.
Platforms can then be included by reference (using repo or
git submodoules)

f1420515a7 irq: Add flags to IRQ_CONNECT_STATIC() macro and irq_connect() function
Flags allow passing IRQ triggering option for x86 architecture.
Each platform defines flags for a particular device and then
device driver uses them when registers the interrupt handler.

The change in API means that device drivers and sample
applications need to use the new API.

IRQ triggering configuration is now handled by device drivers
by using flags passed to interrupt registering API:
IRQ_CONNECT_STATIC() or irq_connect()

0dcad8331b clarify use of term 'context'
The term 'context' is vague and overloaded. Its usage for 'an execution
context' is now referred as such, in both comments and some APIs' names.
When the execution context can only be a fiber or a task (i.e. not an
ISR), it is referred to as a 'thread', again in comments and everywhere
in the code.

APIs that had their names changed:

  - nano_context_id_t is now nano_thread_id_t
  - context_self_get() is now sys_thread_self_get()
  - context_type_get() is now sys_execution_context_type_get()
  - context_custom_data_set/get() are now
    sys_thread_custom_data_set/get()

The 'context' prefix namespace does not have to be reserved by the
kernel anymore.

The Context Control Structure (CCS) data structure is now the Thread
Control Structure (TCS):

  - struct ccs is now struct tcs
  - tCCS is now tTCS

This way, the board initialization routines is placed
to the pure_early_init level to make sure it runs first,
all device initialization procedures run at pure_init level,
so they are initialized early enough to be used for debugging
if needed. Hardware clock initialization is placed on
nano_early_init level to make sure hardware clock is initialized
just before the kernel server starts.

ad2d29689e console: uart_console: decouple uart console init from UART init
With this, the UART console has its own initialization which is not
dependent on UART init routines.

This will allow the app to utilize all UARTs for other purposes,
instead of always reserving one for console. Future patch
will enable this choice.

Note that the console init is effectively demoted to pure_init
from pure_early_init. The UART console depends on UART being
initialized, but there is no deferred init at this point.
So this initializes the console a bit later than UARTs,
simply to make sure the UART is initialized before using it.
Once there is a mechanism for some type of deferred initialization,
the UART console init can be promoted back to pure_early.

2fd29e2667 serial: converting to new driver initialization model
This restructures the device structs and now utilizes the new
driver initialization model. This is another step towards
converting the serial driver to the new driver model.

Note that the serial driver does not initialize the hardware
unless it is being used by another driver. The configuration
of the serial port needs to be done by the driver utilizing
the port (e.g. baud rate, interrupt priority, etc.).
Therefore, some serial ports are declared but not exactly
configured.

Also note that the UART console is being initialized at
the same time as the serial port. This will be removed
in future patch, so the UART console driver will do
its own initialization.

74c8852d05 microkernel: remove kernel service dispatch table
This change removes the internal number-to-function mapping
of microkernel services. Instead, function pointers are used
to specify which service to use.

This is in preparation for private kernel objects. Before this,
only kernel objects that are defined in MDEF files would have
corresponding functions included in the final binary, via sysgen
by populating an array of number-to-function mapping. This
causes an issue when a certain type of objects are all defined
with source code, and never in MDEF file. The corresponding
mapping would be deleted, and the functions are never included
in the binary. For example, if no mutexes are defined in MDEF
file, the _k_mutex_*() functions would not be included.

With this change, any usage of private kernel objects will hint
to the linker that those functions are needed, and should not be
removed from final binary.

f661feee55 IRQ_CONNECT_STATIC implementation for ARM platform
IRQ_CONNECT_STATIC() macro provides static interrupt registration.
It creates an entry for _sw_isr_table, table of interrupt handlers.

IRQ_CONFIG() macro provides interrupt controller configuration.
On ARM platform it configures the priority of each interrupt.

_sw_isr_table is implemented the way that each of it's elements
is located in individual section. Sections are marked a "linkonce",
thus when a device driver declares an interrupt handler, it overwrites
the default _sw_isr_table entry.

API is designed to minimize number of required memory copies.
Application is able to provide new buffer every time it decides to
consume received data. It is also able to just alter offset and
reuse current buffer eg if data was corrupted or otherwise invalid.

808e5c4ba0 Fixes to Kbuild to build on ARM architecture.
This commit fixes issues to allow build on ARM architecture.
- It fixes the include paths in Makefiles.
- It fixes the include path for the offsets.c compilation.
- It fixes the linker command. This changes is needed because gcc
  ARM cross-compiler does not accept an AT() command without
  specifing an address explicitly. This corner case appears
  on ARM architectures when XIP is disabled.

This commit removes the Kconfig symbol KERNEL_DIR.
The symbols was no longer needed because sysgen is only
used on microkernel architectures and the value of
KERNEL_DIR is always "ukernel", therefore it is redundant.

configurations for the following BSPs for microkernel and
nanokernel:

- x86 generic pc
- x86 quark
- arm fsl_frdm_k64f
- arm ti_lm3s6965

They can be applied using the make target defconfig.
This target will generate the corresponding .config
file that will be consumed by the build system.

ea4c3d1c0f bluetooth: UART based driver no longer needs to set regs and irq
Now that UART drivers are configured internally when it comes to
hardware specific information such as IRQ and registers (or mmaped
registers), bluetooth UART driver no longer needs to do it by itself. It
only requires to select the port it wants to use.

UART is configured statically into the driver directly and not anymore
in the board's system.c. Thus limiting the information to be scattered
into 2 files instead of 3. Then in future, it will also be possible to
remove driver specific informations from the generic UART API structure.

a02396098d Eliminate exposure of non-public microkernel structures
Renames the include file defining non-public microkernel structures
from k_struct.h to kernel_structures.h, and relocates it to the
microkernel's non-public include file directory. This means that
applications and drivers including the microkernel's public APIs,
using microkernel.h, can no longer access non-public information.

Note: This change also eliminates some redundant #includes by the
microkernel's own subsystems, since the inclusion of minik.h brings
in the vast majority of public and non-public APIs.

Moves all files in this sub-directory up one level, to the main
nanokernel source directory, then deletes the sub-directory itself.

This change  means that all nanokernel source files (with the
excecption of its include files) are now in the main nanokernel
source directory, which is a more intuitive arrangement.

3c8fb4ac7a Eliminate nanokernel/task sub-directory
Relocates start_task() so that it appears in the main microkernel
directory, alongside its complementary routine abort_task();
this corrects a long-standing anomaly in which this microkernel-
specific routine appeared in the nanokernel portion of the tree.

With this move, the start_task.c file and its parent nanokernel/task
sub-directory no longer serve any purpose and are removed. (Note that
no changes are required for ARC architecture support, which does not
support microkernel capabilities and doesn't use this sub-directory.)

139c856403 Add serial console input handler
Serial console handler when registered allows to interact with serial
line. It can either execute callback from ISR or defer execution to
fiber or task. This will be used in Bluetooth development for tests and
simple interaction with Bluetooth stack.

101d486834 Rename k_args 'Srce' field to 'alloc'
Since multi-node systems are not supported, the 'Srce' field now only serves
one purpose--to indicate whether the packet was allocated from the command
packet pool.  As such, a better name (and type) for it is 'alloc' (of type
'bool') since 'Srce' (of type 'knode_t') suggest multi-node support.

18c8d41bcc Rename _NanoFiberSwap to _nano_fiber_swap
Updating nano kernel functions to follow a consistent naming convention.
Part of that process is the removal of camelCase naming conventions for the
preferred_underscore_method.

Change accomplished with the following script:

#!/bin/bash
echo "Searching for ${1} to replace with ${2}"
find . -type f \( -iname \*.c -o -iname \*.h -o -iname \*.s -o -iname \*.kconf \) \
       -not \( -path host/src/genIdt -prune \) \   \
