When enabling CONFIG_FP_SHARING on ARM, 64 extra bytes are necessary
on the stack of each task in order to save FPU registers S16 to S31.
In the case of the idle stack, the default value of 256 bytes is too
small. As described in ZEP-1470, when the idle task is scheduled out,
floating point registers are saved, which corrupts the stack frame
(especially the saved PC value). When scheduling the idle task, the
restored PC will jump to nowhere, leading to a Usage Fault.
Increase the size of the idle stack by 64 bytes to fix this issue.

Xtensa port uses more stack than others. This was discussed with the team and
we agreed that this can be accepted for the first beta.
We will investigate this later to see how to avoid allocating coproc registers
for the system threads in order to reduce the stack overhead. However this
will not be before the port is considered stable.

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.

k_poll() is similar to the POSIX poll() API in spirit in that it allows
a single thread to monitor multiple events without actively polling
them, but rather pending for one or more to become ready. Such events
can be a direct event, or kernel objects (currently only semaphores and
fifos).
When a kernel object being polled on is ready, it is not "given" to the
poller: the poller must then acquire it via the regular API for the
object (e.g. k_sem_take()). Only one thread can poll on a particular
object at one time. These restrictions mean that k_poll() is most
effective when a single thread monitors multiple events that are not
subject for contention. For example, being the sole reader on multiple
fifos, or the only thread being signalled by multiple semaphores, or a
combination of both.

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.

Some tick frequencies lend themselves to optimized conversions from ms
to ticks and vice-versa.
- 1000Hz which does not need any conversion
- 500Hz, 250Hz, 125Hz where the division/multiplication are a straight
shift since they are power-of-two factors of 1000.
In addition, some more generally used values are made to use optimized
conversion equations rather than the generic one that uses 64-bit math,
and often results in calling compiler intrinsics.
These values are: 100Hz, 50Hz, 25Hz, 20Hz, 10Hz, 1Hz (the last one used
in some testing).
Avoiding the 64-bit math intrisics has the additional benefit, in
addition to increased performance, of using a significant lower amount
of stack space: 52 bytes on ARM Cortex-M and 80 bytes on x86.

By default, kernel event logger is using the system timer. But on
some platforms where the timer driver maintains the system timer
cycle accumulator in software, such as ones using the LOAPIC timer,
the system timer behavior leads to timestamp errors. For example,
the timer interrupt is logged with a wrong timestamp since the HW
timer value has been reset (periodic mode) but accumulated value not
updated yet (done later in the ISR).
This patch is adding the possibility to register a timer callback
function that will be used by the kernel event logger. For example,
on Quark SE, this allows using RTC or AON counter which accuracy is
sufficient and behavior more straight forward compared to system
timer.

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.

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.
