f85566a0b6 misc: add shell support.
Move btshell.h out of samples into include/misc and rename to shell.h

Move btshell.c into driver/console and rename to console_handler_shell.c
as an shell implementation based on new config
CONFIG_CONSOLE_HANDLER_SHELL.

Add shell_register_app_cmd_handler for an to app to optionally call so
that it can receive cmdlines not handled by the cmds registered with
shell_init

714dd9786b clock: add Quark SE clock control
Quark SE provides various clock controllers through its SCSS block.
Peripheral, external, sensor, and others.

This current drivers provides only the clock gating capability, for
peripheral, external and sensor. But it could support divider and more
other features once defined in the generic API.

Note: such clock has _nothing_ to do with a Real Time Clock (RTC).
An RTC provide clock timing like a watch would do. Here the clock
controller is about circuit clocking.

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()

b43758d22a x86: remove dynamically generated IRQ and exception code
We are interested in supporting some XIP x86 platforms which are
unable to fetch CPU instructions from system RAM. This requires
refactoring our dynamic IRQ/exc code which currently synthesizes
assembly language instructions to create IRQ stubs on-the-fly.

Instead, a new approach is taken. Given that the configuration at
build time specifies the number of required stubs, use this
to generate a build time a set of tiny stub functions which simply
push a 'stub id' and then call common dynamic interrupt code.
The handler function and handler argument is saved in a table keyed by
this stub id.

CONFIG_EOI_HANDLER_SUPPORTED removed, the code hasn't been conditionally
compiled for some time and in all cases we call _loapic_eoi() when
finished with an interrupt.

Some other out-of-date verbiage in comments related to supporting
non-APIC removed.

Previously, when dynamic exceptions were created a pointer would
be passed in by the caller reserving ram for the stub code. Since
this is no longer feasible, two new Kconfig options have been added.
CONFIG_NUM_DYNAMIC_EXC_STUBS and CONFIG_NUM_DYNAMIC_EXC_NO_ERR_STUBS
control how many stubs are created for exceptions that push
an error code, and no error code, respectively.

SW Interrupts are no longer triggered by "int <vector>" hard-coded
assembly instructions. Instead this is done by sending a self-directed
inter-processor interrupt from the LOAPIC, using a new API
loapic_int_vect_trigger(). In this way we get rid of dynamically
generated code in irq_test_common.h.

All interrupts call _loapic_eoi() when finished, since this is now
the right thing to do for all IRQs, including SW interrupts.

_irq_handler_set() for x86 no longer requires the old function pointer
to be supplied.

Adds an input hook to be used by the interrupt handler uart_console_isr().
This hook permits the console input to detect a character escape sequence
that can be used to override the console's default input behavior.

This input hook can be set using the following API:
   void uart_irq_input_hook_set(struct device *dev,
                                int (*hook)(struct device *, uint8_t));

The hook returns 1 if the handler should stop processing the character,
and 0 if it should not stop.

ebba3bf38b eth: dw: Add driver for Synopsys DesignWare Ethernet MAC
This patch adds a driver for a Synopsys DesignWare Ethernet MAC.  The
driver uses interrupts to handle received frames, but it uses a
spinloop when transmitting to wait for the transmit descriptor to
become available.  Transmission is coordinated by a fiber, so this
should not result in the system execution being blocked.  Only a
single descriptor is allocated for each of the transmit and receive
directions to save memory and simplify the code.  Another
simplification is that none of the offload capabilities of the
Ethernet device are used.  The driver currently only supports a single
instance of the Ethernet MAC, which is consistent with the limitation
in the network stack that only a single network device is supported.

82f33267c5 Bluetooth: Change fifo_fill to poll_out
The reason why fifo_fill works in qemu but not on real hardware is
that qemu serializes all byte transmission 1 by 1. There is no
real hardware fifo emulated, and "fifo" depth is 1. On real
hardware, the controller owns an internal fifo, with a depth like
8 bytes on Quark x1000. And because of execution flow, how fast is
the controller etc etc... a fifo_fill call might fill in the
internal fifo of 8 bytes and then controller says "I am full"
(which means: "wait for the fifo to have space again"). That's
why poll_out() works: it does the same as fifo_fill and wait
that the internal fifo gets some space again before continuing.
And only when all bytes have been pushed in, it returns.

ad5af93f25 x86: Add context value to loapic_mkstub and ioapic_mkstub macros
Add a context value to the ioapic and loapic mkstub macros to allow
the developer to specify a context value that will be passed on the
stack to the interrupt service routines.

All the invocations for the loapic_mkstub and ioapic_mkstub macros
have been changed to pass in 0 so there is no functional difference
ATM.  This change removes the need for drivers to have trampoline ISR
routines to pass a context vaule to their generic ISR routine.

This is the first step in getting rid of the hack where the driver
needs to look into the __initconfig_* linker objects.

With the introduction of generic transfer function, it is no longer

function to achieve the same result.

The newly introduced i2c_poll_transfer() is now used for register
read for PCAL9535A GPIO driver. The old write then read does not
work because every read or write ends with STOP. However,
the chip requires RESTART after writing the register address.
So the new generic transfer function is perfect for this.

002c53b225 drivers: add shared interrupt driver
This driver allows multiple drivers to share a common interrupt
line. This functionality is required on system that conform to the PC
interrupt structure.  In the context of Zephyr this is needed for
SOC's that have their I/O IP blocks behind a PCI interface. Due to the
limited number of interrupt lines provided by the PCI interface
multiple IP blocks may be configured to share an interrupt line.

Drivers that share interrupts  must be modified to *not* register their
own interrupt service routine as part of their configuration/initialization
but instead bind to the correct instance of this driver by name, then
register their interrupt service routine with this driver.

2709050112 gpio: add driver for PCAL9535A GPIO chip
This adds the driver for I2C-based PCAL9535A GPIO chip.
This currently only enables minimal set of features of the chip for
very simple input/output operations, and does not support interrupt
yet.

2a1e4266e8 IPI console driver with test case
This introduces a generic driver set for console messages routed over
inter-processor interrupt (IPI) channels. These drivers bind to a
low-level IPI driver instance for the actual transport of messages.

ipi_console_sender installs printk and/or stdout hooks to forward
messages over IPI. There is currently no buffering on the sending side.

ipi_console_receiver installs an IPI callback which stashes incoming
characters into a ring buffer, which is monitored by a nanokernel
fiber. The fiber buffers the characters on a per-line basis and sends
them to either printk or stdout. Multiple instances of this driver
may be created in case you need to receive console data from multiple
CPUs.

following order:
- basic hardware initialization;
- devices initialization;
- hardware clock initialization, that the kernel needs to
  run the kernel server.
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.

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.

bbe84f8ae5 Use ccflags-y and asflags-y instead of EXTRA_CFLAGS
According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build.  This patch converts to them to the newer ccflags-y which also
fixes the problem.

e2fa00be6e Algorithm improvement for timer based random number generator
The timer based pseudo random number generator returns the
number of system clock ticks. If the random number function is
called subsequently in a time less than a system clock tick, it
leads to getting same number.

To prevent this the counter is introduced. Counter gets changed
each call, so it ensures the caller gets different numbers each time
the random number function gets called.

c3c75902fe Fix UART on Quark platform
UART on Quark platfor, according to Quark BSP Programmer's
Reference Manual, is located in the following order on PCI bus:
COM2 BAR0: 16550 registers
     BAR1: DMA registers
COM1 BAR0: 16550 registers
     BAR1: DMA registers

So, the driver on Quark platform has to specify BAR (Base
Address Registers) number, the pci_bus_scan() function looks for.

As long as UART is a concole device, calling pci_show() during
it's initialization does not make any output.

627155afeb PCI scan by BAR number
Added BAR (Base Address Registers) as a parameter for PCI scan.
Some devices (as UART in Quark) use two set of BARs for different
purposes. A driver may require only one of them.

BARs are numbered from 0 to PCI_MAX_BARS.
PCI_BAR_ANY means ignore the BAR number. Constants are defined
in drivers/pci.h

If device class is not specified as a scanning parameter, and
set to 0, ignore it.

d3a4177d92 pci: Provide a simpler yet powerful PCI enumeration API
This fixes many issues around PCI enumeration from old API:
- a static internal table was fed with scanning results, thus eating
  memory, and worse: due to the limit of its size, scanning for new
  classes was impossible unless growing statically the size of this
  table --> more memory eaten! Not to mention PCI enumeration is done
  once at boot time for driver initialization and that's all, so this
  table is hanging around for nothing afterwards.
- one needs first to scan a class, then maybe he will be able to find
  his device via pci_dev_find. Where all could be done at once.
- pci_dev_find was not trustworthy due again to the internal table. Now
  if the device is not found, one will know it really went through all
  the possbilities.
- still let the possibility for hard-coded BARs value on driver side
  (thus no PCI scan required). However this is greatly advised not to do
  so as BARs might change over a firmware/BIOS update.

Comparison:

old pci_dev_scan: could only filter out via class mask.
new pci_dev_scan: can filter out via a class, a vendor and device ID
(it could easily do the same for Function and BAR index as these are
usually fixed and informed through datasheet)

old pci_dev_scan: was limited in its findings by the size of the
internal result table.
new pci_dev_scan: can proceed through all the buses and devices every
time (there are optimizations to avoid useless work of course)

old results did not tell about the function or BAR index.
new one tells, and the structure has not bloated.

old internal code: was storing a big table of results
new internal code: is only storing a small lookup structure and an
array of Bus:Dev pairs for each PCI class for optimizations purpose.
(though, if needed, we could disable this through some #ifdef)

Usage:

- Have a local struct dev_info
- Fill it with what you want to look for, currently: only class and
  vendor_id/device_id. Function and BAR index could be added if needed.
- Call pci_bus_scan_init(): this will reset the internal lookup
  structure.
- Call pci_dev_scan(<a pointer to your dev_info>): at first call, the
  internal lookup structure will pick up the informations from dev_info
  and will try to find out what has been requested. It will return 1 on
  success, or 0. On 1, your dev_info structure will be updated with the
  found informations. If more devices can be found against the same
  lookup informations, just call again pci_dev_scan(<a pointer to your
  dev_info>) as long as it returns 1. When 0 is hit, it will mean you
  found all.

Some checkpatch issues were solved by scripts leaving other problems
such as alignment and indentation issues.  In order to comply with the

- Fixed the function declaration moving the parameters' comments above
  the function in accordance to the doxygen format.
- Fixed functions' opening and closing brackets. These brackets should
  not be indented.
- Fixed the 'if', 'for' and 'while' statements adding the brackets
  around the sentence.
- Fixed comments' alignment.
- Fixed indentation.

The work was done manually and submitted as one commit. I didn't
separate these changes in different commits because they were fixed all
at once. Basically, all errors were fixed in every file at once.

099ecbfa7c Bluetooth: Add minimum required length parameter to bt_uart_read()
There are some places where it's forgivable if bt_uart_read() wasn't
able to read as many bytes as requested. In other places it's not
acceptable (e.g. when reading ACL or event header). To avoid failing
in situations where we can handle receiving less data than requested
this patch adds a new parameter to bt_uart_read() to specify the
minimum required data amount.

935198e715 Bluetooth: Fix UART driver robustness when out of buffers
If we're out of buffers the UART driver would previously loose sync of
where the packet boundaries go, because it was using the buffer itself
to store and parse the HCI packet headers. This patch modifies the
UART driver to use stack variable for initial header parsing, thereby
being able to always determine how many remaining bytes there are and
cleanly discard the bytes until the beginning of the next packet.

the number of 'get' function growing too large consolidate the

consolidated function also takes the type as input parameter so that
we know this from the very start and thereby plan for the split into
multiple buffer pools.

2581ad9313 Bluetooth: Add HCI UART (H4) driver
This patch adds a simple HCI UART (H4) driver that currently maps to
the second UART in the system. The main intention is to use this
together with qemu for accessing the Bluetooth controller available on
the host OS side.

The H4 HCI transport protocol is perhaps the simplest of the standard
HCI transports. It consists of a single byte in the beginning of each
packet which indicates the type of the packet: HCI event, HCI command,
ACL data, or SCO data (which we don't use at the moment).
