Peter Mitsis b58878bb89 kernel: Init back pointer to microkernel task
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.

Andrew Boie 68b3b6135e errno: implement _get_errno() in common code
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.

Geoff Thorpe 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.)

Anas Nashif 7c27d8ab3a soc: arm: add Makefiles one level up
It was not possible to add directories under an SoC family
because of the direct call to Makefile in the SoC series from the
architecture level.

While we have SoC still using the old structure, add a conditional
to still support old structure and allow Makefiles directly under
an SoC family directory. 

This is useful for adding drivers and BSP files common to one family.

Johan Hedberg 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
(in this case printk/printf get encoded to the monitor protocol).

Daniel Leung 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.

Daniel Leung 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.
