Adds the nanokernel infrastructure to permit microkernel tasks
to block/unblock on nanokernel objects. Multiple tasks may wait
on a nanokernel object's dedicated task wait queue.
It is important to note that when data is posted to the object
all the tasks on that object's dedicated task wait queue may be
woken up but the data is not immediately given to any of the tasks.
This is done to maintain consistent behavior with the nanokernel
as in a nanokernel system, fibers are given preference in both
waiting on and getting data from a nanokernel object.

Adds the microkernel infrastructure to permit a microkernel task
to [un]block on a nanokernel object. Unlike tasks that [un]block
on microkernel objects, the work for [un]blocking tasks on nanokernel
objects will not always be done in the kernel service fiber. One of
the repercussions of this is that in many cases the microkernel task
scheduler must be explicitly invoked (by issuing a no-op kernel
service call).

Fibers initialize this back pointer to NULL as they are (by definition)
not microkernel tasks. Microkernel tasks initialize it to their
corresponding 'ktask_t'.
However for nanokernel systems, the back pointer is always NULL. This
is because there is only one task in a nanokernel system (the background
task) and it can not pend on a nanokernel object--it must poll.

We really should have more faith in the compiler, it generates
code to implement this exactly like the arch-specific assembly
versions, and on ARM is actually 4 bytes shorter.
FUNC_NO_FP used to disable the usual C preamble to update the
frame/stack pointers, which is how the sizes are still the same
or less. It's debatable how useful the occasional use of
FUNC_NO_FP is in practice since it hinders debugging and in a
production build frame pointers should be globally disabled, but
we can address that later.

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.)

Certain Low power SOC states (e.g. deep sleep) will result in device
IP blocks losing state. In such a scenario it can be useful to have
a mechanism for devices (driver code) to signal the power manager /
policy that they are in the middle of a transaction.
We expect the device driver code to make a call to
device_busy_set(device *) before initiating a transaction and
device_busy_clear(device *) on completion. It is expected that device
driver developers will add this as necessary in their drivers.
Further an API is provided for power manager application / policy to
check this. Based on this the power manager / policy can decide
whether or not to go into a particular power state.

This changes the behavior of device_get_binding() so that
it returns NULL if driver_api is not set. This provides
a way for driver to state that it has not been initialized
properly, and prevents app from using it since no reference
to the device struct will be returned.
This implements the idea specified in [1]. The idea is to
reuse an existing resource by piggy-backing onto driver_api,
thus avoiding an extra "device state" variable in the device
struct. This differs from the code specified in the mailing
list by checking driver_api for NULL first. This avoids
the unnecessary strcmp() if driver_api is NULL.

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.

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.

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
through the first parameter of the thread.
This allows a debugger application to access the information directly
from the thread context structures list.

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.

This is being removed for a few reasons:
- AFAICT this is the only API in Zephyr that follows an allocate/free
model.
- There are no public APIs in the interrupt subsystem for releasing
or reconfiguring an interrupt. This code was relying on arch-specific
private APIs. If we really want to keep this capability we should
make these APIs public and consistent across arches.
- The use-case for this API is not clear, as Zephyr is not intended
for hot-pluggable peripherals. Built-in hardware tends to need its
interrupt for its entire life cycle.
- The current implementation of dynamic interrupts on x86 does not
support freeing a dynamic IRQ that was reserved with
irq_connect_dynamic(), causing this code not to work. To add this
would require reimplementing _get_dynamic_stub() to use a bitfield
or set of bitfields to track unused stubs rather than the simple
counter it uses now.

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

Simplifies the nanokernel timer API so that the timeout parameter must be
specified when invoking nano_isr_timer_test(), nano_fiber_timer_test(),
nano_task_timer_test() and nano_timer_test().
This obsoletes the following APIs:
nano_fiber_timer_wait()
nano_task_timer_wait()
nano_timer_wait()
Note that even the though the new API requires that the timeout parameter
be specified, there are currentl only two acceptable values:
TICKS_NONE and TICKS_UNLIMITED
Theoretically, the current implementation would allow one to supply a
finite positive value for the timeout and the system would wait up to
that many ticks for the timer to expire. However, it is thought that
that unnecessarily complicates the nanokernel timer model and so it is
left as an unsupported option. Should that change, then that feature
could be enabled by updating the documentation.

This patch enables defining microkernel events within source code.
This is similar to other private kernel object patches.
The test has been modified a little bit due to the fact that
the event ID is now a memory address, instead of numeric ID.

Reworks the internal design of a command packet set so that
the command packet array is split out into a separate variable
lying in uninitialized memory. This shrinks the command packet's
data section footprint to almost nothing.
Note: A side effect of this change is that it is no longer possible
to define a command packet set as a "static" variable since the
CMD_PKT_SET_INSTANCE() macro now generates two variables.

Provides a way for a fiber or task to busy wait for a specified
period of time. This is useful in situations where a delay needs
to be performed without switching execution to another context,
such as:
1) It would take longer to switch to another context and then switch
back again than to simply busy wait.
2) A delay is required by the kernel's main task (i.e. the nanokernel's
background task or the microkernel's idle task). This task is not
allowed to voluntarily relinquish the CPU because this would leave
the kernel with nothing to execute in its place.

Revises microkernel initialization code by incorporating the existing
_k_kernel_init() and main() routines into _main(). This optimizes kernel
initialization a bit, and allows application code to use main()
if desired -- for example, as the entry point to an application task.
The change also eliminates the need for sysgen to generate a routine
whose content is always the same.
This change preserves the existing order of operations done during
kernel initialization, and leaves further improvements for later.

Due to similar padding issue as pipe, the list of task object
may not be used directly. As mentioned before, some compiler/linker
may pad the large struct. For example, compiling under gcc and
march=i686 pads the struct to 32-byte alignment (march=atom to
64-byte alignment). This causes issue with sizeof() and pointer
arithmetic because they have no idea about the padding.
When the stars align in a certain way, these task structs may be
corrupted. So add a task pointer list and use it for task
manipulation. The task list remains as it is beneficial to group
them together to take advantage of cache locality.

Update the documentation of _thread_exit() to reflect the fact that a
task can call it if it does so with interrupts locked. A task or another
fiber cannot preempt a fiber, so a fiber can still call _thread_exit()
without locking interrupts. If a task locks interupts first then calls
it, no fiber or other task can preempt it either.

count is stored in the ring buffer's value field. The data size only
refers to the extra data attached to the message and NOT any internal
representation of metadata inside the ring buffer, the event_logger

This patch is based on some code contributed by Dirk Brandewie.
This is a generic data structure for queuing data in a FIFO ring
buffer. Any given data enqueued is annotated with an app-specific
type identifier, and small integral value. Use of a data pointer
is optional if the necessary information can be conveyed in the
annotations. We want all the metadata to fit in a single DWORD.
The ring buffer always contains at least one free dword in the
buffer to correctly distinguish between full and empty queues.
Concurrency control is almost nonexistent; depending on usage,
apps may want to introduce the usage of semaphores and/or mutexes
to preserve the integrity of the ring buffer or provide notifications
when data is available.

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

k_proc was a legacy leftover that does not make any sense, since there
is no concept of a "process" in the system. Rather, that data structure
refers to a 'task control block', i.e. the representation of a task
execution context from the microkernel's point-of-view (not to confuse
with the 'struct ccs', the representation of a thread execution context,
from the nanokernel's point-of-view).

Basically, this does not work anymore:
task_timer_start(<timer>, 0, X, <sem>);
since it does not make much sense to have a timer with an expiry of 0
ticks. The code internally was setting the duration to be equal to the
period anyway. So, to achieve the same behaviour, do this:
task_timer_start(<timer>, X, X, <sem>);
This has the positive side-effect of removing a small block of logic
that was handling the cases where duration was 0.

irq_handler_set, irq_priority_set and irq_disconnect have been made
private by prepending an underscore to their names:
irq_handler_set -> irq_handler_set
irq_priority_set -> irq_priority_set
irq_disconnect -> irq_disconnect
The prototypes have been removed from header files when possible, and
extern statements used in C code where they were called.
_irq_priority_set() for ARM is still in the header file because
IRQ_CONFIG() relies on it.

Previous names, focusing on 'async', were misleading, because:
- some of those APIs can be used synchronously as well
- other APIs can also do asynchronous transfer, and don't have 'async'
in their names
- the key concept of these APIs is that they use memory pool blocks
rather than raw data buffers.

To support private pipe objects (aka, defining pipes within

This is done by creating a new section in binary, and all pipe
pointers go into this section. By doing this, the pipe list
can still be manipulated as an array. The reason behind
putting the pointers to pipe, instead of the pipe objects
themselves, is that some compiler/linker may pad the large pipe
struct. For example, compiling under gcc and march=i686 pads
the struct to 32-byte alignment (march=atom to 64-byte alignment).
This causes issue with sizeof() and pointer arithmetic because
they have no idea about the padding. So use pointers here to
prevent padding.

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.

The size of the k_args strcture must be equivalent to ...
CMD_PKT_SIZE_IN_WORDS * sizeof(uint32_t)
This is complicated by the fact that not only do different compilers treat the
size of 'bool' and 'enum' types differently, they may also pad structures
differently. Both of these differences have direct impacts on the k_args
structure. To work around this, the k_args fields 'alloc' and 'Comm' are
forcibly aligned to a 4-byte boundary, while the rest of the k_args structure

(due to it being passed a properly aligned stack), there is no longer any

Furthermore, as a direct result of the properly aligned stack, the pointer to
the new context does not need to be passed as a separate parameter since it

Routines are no longer flagged as constructors using the FUNC_CONSTRUCT(level)
macro. This is because some compilers do not support constructor levels.
To indicate that a routine should be a constructor, the SYS_PREKERNEL_INIT()
macro should be used AFTER the definition of the routine. For example ...
void my_library_init(void)
{
...
}
SYS_PREKERNEL_INIT(my_library_init, 500);
The first parameter to SYS_PREKERNEL_INIT() is the name of the routine. The
second is the priority level (000...999). The lower the number, the higher
the priority. NOTE: It is important that all three digits are specified;
otherwise the linker may put the constructors in an undesired order.
