We had two assembly files to prepare for entry into C domain,
one intended for the simulator and one intended for real boards.
- Both files merged into a single crt1.S for either simulated or real
targets
- Extra logic to populate command line arguments from simulator removed,
we don't use it.
- BSS zeroing logic from crt1-boards.S used
- Reference to missing reset-unneeded.S removed
- exit() implementation moved to fatal.c, now invokes a kernel panic
if we are not running under the simulator

This adds support for the nRF51 chip on the board.
If you'd like to run Zephyr on the STM32F4 chip on Carbon, you need to
use the 96b_carbon board instead.
The current SPI Bluetooth protocol only uses 5 wires, so we use the
remaining pin as UART TX.

The computation of unused stack space is now split off from the function
which sends the result to printk().
The code now assumes that the struct k_thread is stored elsewhere.
Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
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.

Building zephyr for xtensa with gcc requires additional include paths and
additional library (libhal).
Add xtensa sysroot and include paths to CFLAGS when building for xtensa.
The root Makefile then does the right thing adding these parameters to
KBUILD_CFLAGS and KBUILD_ASFLAGS.
Add xtensa libhal to the TOOLCHAIN_LIBS_xtensa. Modify TOOLICHAIN_LIBS to
include arch-specific libraries.
Seems that it would be nice to have TOOLCHAIN_CFLAGS_$(ARCH) with the
same behavior as TOOLCHAIN_LIBS_$(ARCH). It also seems that the SYSROOT
definition doesn't have to be restricted to MAKEFILE_TOOLCHAIN_DO_PASS2.

This reverts commit 698de88916 ("Bluetooth: controller:
Cleanup redundant ticker busy loop")
Scan enable asserted in ctrl.c line 3756 due to the fact that a
role event was active and ticker job has hence been disabled.
Add back the busy loop so that scan enable can wait until the
active role event completes gracefully.
The ticker busy loop is mandatory in all ticker interface calls
if a blocking behavior is desired.

Added because previously, Zephyr used API incompatible with Newlib
for errno handling. Even with Newlib compatibility changes, we
override the function which is defined in Zephyr SDK libc.a, so
makes sense to ensure thsi works as expected.

Newlib names this function __errno(), so if we want Zephyr to work
with Newlib seamlessly, it's better to just follow Newlib's naming

Currently, a queue/fifo getter chooses how long to wait for an
element. But there are scenarios when putter would know better,
there should be a way to expire getter's timeout to make it run
again. k_queue_cancel_wait() and k_fifo_cancel_wait() functions
do just that. They cause corresponding *_get() functions to return
with NULL value, as if timeout expired on getter's side (even
K_FOREVER).
This can be used to signal out of band conditions from putter to
getter, e.g. end of processing, error, configuration change, etc.
A specific event would be communicated to getter by other means
(e.g. using existing shared context structures).
Without this call, achieving the same effect would require e.g.
calling k_fifo_put() with a pointer to a special sentinal memory
structure - such structure would need to be allocated somewhere
and somehow, and getter would need to recognize it from a normal
data item. Having cancel_wait() functions offers an elegant
alternative. From this perspective, these calls can be seen as
an equivalent to e.g. k_fifo_put(fifo, NULL), except that such
call won't work in practice.

Commit 58c8d15 ("clock control:stm32: provide STM32Cube LL based
driver") added PLL initialization which disables the PLL before
configuring it.
This works if the system clock source is not the PLL (which is the
usual case for Zephyr booting out of chip reset). However, if the
SYSCLK source *is* the PLL, this halts execution.
To support this use case, switch the SYSCLK source to the
always-present HSI before disabling the PLL.
