8cc716792a renamed this variable to lower
case to indicate it's only used locally however WEST_ARG is used as a
parameter of zephyr_module.py in CMakeLists.txt when
CONFIG_BUILD_OUTPUT_META is enabled.
This variable was used when west had some limitation. It does not
really make sense now, so it has been removed and content of west_arg
variable has been added by default.

Fix the init_prioties related cmake targets so they also
work with native_simulator based build targets.
Mostly this consists of pointing to the right file
(final build result instead of intermediate elf library)
and setting the dependency to that final build result.
Note that for the native_simulator based targets
the init priorities check can only be run on build
if we are building the final image (not just a partial
prelinked library),
and we are not assembling several images together
into one executable.

Several paths are checked for existence before added as global Zephyr
include path.
The existence check was needed because some tooling emit warnings on
non-existing paths.
Only few SoCs are using those pre-defined paths, yet this code runs
for all SoCs. The principle originates back from Kbuild days, and with
CMake it's more common and generally more visible to let the CMake code
defining libraries to specify include paths.
Furthermore it appears that several SoC implementation following the
<soc-path>/include was unaware that the path would be automatically
added as include path, cause they contain lines like:
zephyr_library_include_directories(include)
Remove pre-defineds path except the `<SOC_PATH>` path, which is
guaranteed to exists.
This simplifies the CMake logic in the top-level Zephyr CMakeLists.txt
file.
This cleanup further prepares for future work where SoCs need not to
be organised under architectures which is important for multi-arch SoCs.

Since bb590b5b6e introduced ordinals in the priority sequence, the "same
priority" case cannot happen anymore, furthermore the priority value in
the script is now the position of the function in the init sequence, so
if two devices have the same priority there's something real bad going
on.
Drop all the "same priority" handling code and tests, convert the case
into ane exception instead. Drop the init stubs as well from the test,
they are not required anymore.

This commit updates the handling of board and SoC linker scripts.
Several SoCs creates a linker.ld file which sole purpose is to include
another arch common linker script, often with content like this:
#include <arch>/linker.ld
instead of 100+ SoC specific linker.ld files containing just a single
include line of above structure, then this commit introduces two now
CMake variables, BOARD_LINKER_SCRIPT and SOC_LINKER_SCRIPT.
This allows the board and SoC CMake code to point directly to a common
linker script instead of creating a dummy linker.ld file doing this.
This removes the need for several dummy linker.ld file.

This should make the script more robust in case of stale files in the

This enables -Wshadow to warn about shadow variables on
in tree code under arch/, boards/, drivers/, kernel/,
lib/, soc/, and subsys/.
Note that this does not enable it globally because
out-of-tree modules will probably take some time to fix
(or not at all depending on the project), and it would be
great to avoid introduction of any new shadow variables
in the meantime.
Also note that this tries to be done in a minimally
invasive way so it is easy to revert when we enable
-Wshadow globally. Source files under modules/, samples/
and tests/ are currently excluded because there does not
seem to be a trivial way to add -Wshadow there without
going through all CMakeLists.txt to add the option
(as there are 1000+ files to change).

This property specifies the flag used to pass the linker script filename
through the compiler front end tot he linker.
For clang, we use the general purpose linker-pass through -Wl flag with -T:
-Wl,-T as clang doesn't support -T.
For gcc, we use -T directly as this keeps the picolibc specs file from
inserting the picolibc linker script as well.
If the compiler doesn't specify a value, we continue to use -Wl,-T as
before.

When building a native library there is a few options
we cannot pass to the compiler and linker,
including instructing them to genrate non PIE code
(as it is still to early to say that),
or garbage collect unused sections (as we are not yet doing

We also need to provide different

The syscall generation phase parses all header files to look
for potential syscalls, and emits all the relevant files to
enable syscalls. However, this results in all the syscall
marshalling functions being included in the final binary.
This is due to these functions being referred to inside
the dispatch list, resulting in ineffective garbage
collection during linking. Previous commits allows each
drivers and subsystems to specify which header files
containing syscalls are relevant. So this commit changes
the syscall generation to only include the syscalls needed
for the build in the syscall dispatch list and removing
various bits related to that. This allows the linker to
garbage collect unused syscall related function, and thus
reducing final binary size.

The current approach of failing the build on ztest with no optimization
broke coverage builds, and generally raised some concerns about being
too aggressive.
Downgrade the error to a warning and rework the option to inhibit the
warning, while also dropping it automatically for POSIX (that are not
really affected by stack size) and coverage run (that always runs with
no optimization).
Will reconsider this down the road if we still see issues filed for the
tests broken with no optimization and no further tuning.

This adds a new linker property specifically for passing
"-no-pie" to linker. Older binutils' LD (<= 2.36) do not
support this flag and will behave erratically if set. It
would parse "-no-pie" separately as "-n" and "-o-pie",
which would result in the output file being "-pie"
instead of "zephyr*.elf". Moreover, LLVM lld does not
support -no-pie but --no-pie (note the extra hyphen).
By having no-pie as a linker property, we can pass
correct no-pie flag to these linkers (or none at all).

The oneApi support has bit rotten since it was first introduced. Update
the support to function with the latest 2023.0.0 release and add a
check to only support that version or newer for now. Versions before
2021.2.0 have linker script failures.
Various fixes made:
* In the 2023.0.0 release, various binaries are in a llvm-bin path so
add support to search in that path. This replaces the python search
path that much older versions needed.
* newlib isn't supported with oneApi so set TOOLCHAIN_HAS_NEWLIB to
OFF to match that.
* 2023.0.0 doesn't back llvm-nm, so use binutils version. This
is expected to be fixed in 2023.1.0 release so add a check to
handle either case.
* Update compiler flag check based on clang to also support
CMAKE_C_COMPILER_ID of "IntelLLVM" as that is how the oneApi toolchain
reports itself.
