Youvedeep Singh 7f2aaedfd7 arch: arm: store/restore regs r0-r3 while making function call.
In benchmark test (test_info) while making function call regs
r0 - r4 are modified into called function. Due to this value
inside r3 is getting lost.
This patch saves and restore the value in r0-r4 regs while making
function calls from assembly language.

Youvedeep Singh 76b577e180 tests: benchmark: timing_info: Change API/variable Name.
The API/Variable names in timing_info looks very speicific to
platform (like systick etc), whereas these variabled are used
across platforms (nrf/arm/quark).
So this patch :-
1. changing API/Variable names to generic one.
2. Creating some of Macros whose implimentation is platform
depenent.

Paul Sokolovsky 70772add28 arch/arm/core: In comments, consistently refer to "Cortex-M".
This directory now handles all of Cortex-M0, Cortex-M3/M4. So, just
consistently use "Cortex-M" (as used by number of files already)
without refering to a particular subarch. Also, consistently (letter
casing) spell it as "Cortex-M". A typo is fixed too.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Marcus Shawcroft e2d3cc4b81 arm: Restructure ARM cpu related preprocessor conditionals.
The ARM code base provides for three mutually exclusive ARM
architecture related conditional compilation choices.  M0_M0PLUS,
M3_M4 and M7.  Throughout the code base we have conditional
compilation gated around these three choices.  Adjust the form of this
conditional compilation to adopt a uniform structure.  The uniform
structure always selects code based on the definition of an
appropriate config option rather the the absence of a definition.

Removing the extensive use of #else ensures that when support for
other ARM architecture versions is added we get hard compilation
failures rather than attempting to compile inappropriate code for the
added architecture with unexpected runtime consequences.

Adopting this uniform structure makes it straight forward to replace
the adhoc CPU_CORTEX_M3_M4 and CPU_CORTEX_M0_M0PLUS configuration
variables with ones that directly represent the actual underlying ARM
architectures we provide support for.  This change also paves the way
for folding adhoc conditional compilation related to CPU_CORTEX_M7
directly in support for ARMv7-M.

This change is mechanical in nature involving two transforms:

1)

  #if !defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  ...

is transformed to:

  #if defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  #elif defined(CONFIG_CPU_CORTEX_M3_M4) || defined(CONFIG_CPU_CORTEX_M7)
  ...

2)

  #if defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  ...
  #else
  ...
  #endif

is transformed to:

  #if defined(CONFIG_CPU_CORTEX_M0_M0PLUS)
  ...
  #elif defined(CONFIG_CPU_CORTEX_M3_M4) || defined(CONFIG_CPU_CORTEX_M7)
  ...
  #else
  #error Unknown ARM architecture
  #endif

Anas Nashif 5ad2905532 arm: remove old GDB_INFO support
That module is not used anymore: it was introduced pre-Zephyr to add
some kind of awareness when debugging ARM Cortex-M3 code with GDB but
was never really used by anyone. It has bitrotted, and with the recent
move of the tTCS and tNANO data structures to common _kernel and
k_thread, it does not even compile anymore.

Benjamin Walsh f6ca7de09c kernel/arch: consolidate tTCS and TNANO definitions
There was a lot of duplication between architectures for the definition
of threads and the "nanokernel" guts. These have been consolidated.

Now, a common file kernel/unified/include/kernel_structs.h holds the
common definitions. Architectures provide two files to complement it:
kernel_arch_data.h and kernel_arch_func.h. The first one contains at
least the struct _thread_arch and struct _kernel_arch data structures,
as well as the struct _callee_saved and struct _caller_saved register
layouts. The second file contains anything that needs what is provided
by the common stuff in kernel_structs.h. Those two files are only meant
to be included in kernel_structs.h in very specific locations.

The thread data structure has been separated into three major parts:
common struct _thread_base and struct k_thread, and arch-specific struct
_thread_arch. The first and third ones are included in the second.

The struct s_NANO data structure has been split into two: common struct
_kernel and arch-specific struct _kernel_arch. The latter is included in
the former.

Offsets files have also changed: nano_offsets.h has been renamed
kernel_offsets.h and is still included by the arch-specific offsets.c.
Also, since the thread and kernel data structures are now made of
sub-structures, offsets have to be added to make up the full offset.
Some of these additions have been consolidated in shorter symbols,
available from kernel/unified/include/offsets_short.h, which includes an
arch-specific offsets_arch_short.h. Most of the code include
offsets_short.h now instead of offsets.h.
