Torsten Rasmussen 3d76ee8f25 cmake: provide CMake helper macros for argument validation
This commit provides a number of helper macros for verifying arguments
passing to function:
- zephyr_check_flags_required
- zephyr_check_arguments_required
- zephyr_check_arguments_required_all
- zephyr_check_flags_exclusive
- zephyr_check_arguments_exclusive

which facilitates checking whether a required argument or flag has been
given or if mutual exclusive arguments are given.

Jamie McCrae df9027a64a sysbuild: support Zephyr modules
This commit extends the Zephyr module yaml scheme with additional
entries for sysbuild in the build section.

This allows for Zephyr modules to extend the sysbuild infrastructure
by providing additional CMake and Kconfig files to be included in
sysbuild.

The new settings are:
build:
  sysbuild-cmake: <path>
  sysbuild-kconfig: <path>/<file>
  sysbuild-ext: <true>|<false>
  sysbuild-kconfig-ext:  <true>|<false>

those settings follow the same pattern as the equivalent Zephyr build
settings but are processed by sysbuild.

Martí Bolívar 0a1a5f8ab8 cmake: modules: west: allow custom MIN_WEST_VERSION
Different users of the Zephyr CMake package may have different minimum
required versions of west. One important in-tree example is the
documentation, which must either be built with the latest version of
west, or with no west installed at all.

Make the MIN_WEST_VERSION variable configurable to support use cases
like this.

Torsten Rasmussen 3a9b2a3e83 cmake: recommend CMake >=3.20.5 as minimum CMake version
CMake versions <3.20.5 contains the following bug:
https://gitlab.kitware.com/cmake/cmake/-/issues/22310

This bug was fixed in CMake 3.20.5:
https://gitlab.kitware.com/cmake/cmake/-/merge_requests/6232

Generally Zephyr can build with CMake >=3.20.0, however the
`cmake/package_helper.cmake` is impacted by the above issue.

Therefore, specifically request CMake >=3.20.5 for package helper
and update documentation to recommend CMake version 3.20.5 in order
to minimize risk of users being impacted by this bug.

Users invoking package helper with CMake 3.20.0-3.20.4 will see:
> CMake Error at cmake/package_helper.cmake:45 (cmake_minimum_required):
>  CMake 3.20.5 or higher is required.  You are running version 3.20.x

Rest of Zephyr still builds with CMake versions >=3.20.0.

Marcin Niestroj b03d27cca3 toolchain: esp32: support esp32s3 in 'espressif' toolchain
CROSS_COMPILE_TARGET is defined based on CONFIG_SOC selected. So far
'esp32s3' SoC was not taken into account, so building Zephyr with
'espressif' toolchain (the only one supported for now) is was not possible
out of the box.

Add 'CROSS_COMPILE_TARGET_xtensa_esp32s3' CMake variable, same as it is
done for other SoC specific variables. That way toolchain paths are

Torsten Rasmussen 45b25e5508 cmake: dereference ${check} after zephyr_check_compiler_flag() call
Follow-up: #53124

The PR#53124 fixed an issue where the variable `check` was not properly
dereferenced into the correct variable name for return value storage.
This was corrected in 04a27651ea.

However, some code was passing a return argument as:
`zephyr_check_compiler_flag(... ${check})`
but checking the result like:
`if(${check})`
thus relying on a faulty behavior of code updating `check` and not the
`${check}` variable.

Fix this by updating to use `${${check}}` as that will point to the
correct return value.

Andy Ross 728230a241 cmake/compiler: Limit warning flag usage to compatible toolchains
New C++ versions have deprecated "register" variables and restricted
"volatile" semantics, so new gcc's will emit warnings when they see
that syntax.  Zephyr uses both in our C headers (though we should
probably get rid of register and unify with C++'s volatile model), so
we're disabling the resulting warnings.

But OLD gcc variants (like xcc, sigh) don't understand new -Wvolatile
and -Wregister on the command line, so they get confused.  Limit the
uses to the standard versions for which gcc would emit warnigns; xcc
doesn't support those anyway.

Kumar Gala 2d12766e78 toolchain: oneApi: Fix support and update for 2023.0.0 release
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.

Torsten Rasmussen 91902c5fd4 cmake: add sparse support to the new SCA infrastructure
Sparse support was original introduced in #43776.

This commit introduces sparse support as part of Zephyr SCA tool
infrastructure.

The implementation in this commit has some benefits over existing
support:
- It does not required users to set `REAL_CC` in environment before
  invoking build command.
  This reduces risk of user mistakes, such as
  - REAL_CC being different from CMAKE_C_COMPILER.
  - User running CMake in one terminal / environment where REAL_CC is
    defined but invoking the build command in a different terminal /
    environment where REAL_CC is not defined or defined differently.
- It improve user experience as the user no longer has to define /
  re-define REAL_CC when building for different architecture, like
  switching from arm to xtensa, as this is now handled in CMake.
- CMAKE_C_COMPILER is not overwriting, this can be important for other
  tools which calls the C compiler for pre-processing purposes, such
  as devicetree and linker script generation.

Torsten Rasmussen cb690ec56e cmake: implement build infrastructure for supporting SCA tools.
Static code analyser (SCA) tools are important in software development.

CMake offers built-in support for some tools, such as cppcheck and
clang-tidy.

Other tools, such as sparse, are not directly supported.

This commit provides a uniform way for users to specify a supported
SCA using `ZEPHYR_SCA_VARIANT=<tool>` which is consistent with how
toolchains are specified.
ZEPHYR_SCA_VARIANT can be set using `-D` or in environment.

Support for an SCA tool is done in `cmake/sca/<tool>/sca.cmake`.
SCA_ROOT can be used to specify additional search paths when looking up
implementation for a tool. SCA_ROOT can also be specified in
`zephyr/module.yml` as setting. This makes it possible to provide SCA
tool implementation as part of a Zephyr module.

Alternatively, files can be passed as a space separated list

flexibility when relocating files. Glob matching functionality is still
available, although the preferred method to do this would now be:

file(GLOB relocate_sources "src/*.c")

In case of building with minimal libc (provided by Zephyr)
we rely on minimal libc headers and manually specify

Yuval Peress fae9923ff2 unittest: update coverage library non gcc toolchains
When building with clang, the unittests were giving us an error:
```

This seems to be from linking in `gcov` regardless of the toolchain.
It appears that clang doesn't need any special library for coverage.
With this change the following now produce identical coverage reports:

Tom Burdick e3d877f811 rtio: Userspace support
Add support for userspace with RTIO by making rtio and rtio_iodev
k_objects. As well as adding three syscalls for copying in submissions,
copying out completions, and starting tasks with submit.

For the small devices Zephyr typically runs on one of the most important
attributes tends to be low memory usage. To maintain the low footprint of
RTIO and its current executor implementations the rings are not shared with
userspace. Sharing the rings it turns out would require copying submissions
before working with them to avoid TOCTOU issues.

The API could still support shared rings in the future so that a
kernel thread could directly poll, copy, verify, and start the submitted
work. This would require a third executor implementation that maintains its
own copy of submissions similiar to how io_uring in Linux works.

Stephanos Ioannidis 9f652ea04a cmake: gcc: Fix Cortex-R52 FPU type
The commit f10fa0dea8 mapped the
Cortex-R52 processor type to use the "VFPv3" FPU type, but the
toolchain requires the "FPv5" FPU type and refuses to assemble
floating-point instructions when the "VFPv3" FPU type is specified.

This commit updates the build script to specify the FPU type of
`fpv5-sp-d16` when the processor is configured with a single-precision
FPU, and `neon-fp-armv8` when the processor is configured with a
double-precision + Advanced SIMD-capable FPU.

Note that the `fp-armv8` FPU type is an alias for double-precision FPv5
with 32 double-precision registers (refer to the GCC
`gcc/config/arm/arm-cpus.in` for more details); NEON is always
specified in case of a double-precision configuration because the
Cortex-R52 can only be configured as such.

This commit introduces the possibility of a sample to locate

MCUboot.

This allows use-cases where a sample, A, want to include MCUboot but has
adjustments to the default MCUboot configuration.

By adding a Kconfig fragment `<sample>/sysbuild/mcuboot.conf`, then that
fragment will be used together with the default configuration for
MCUboot.

It is also possible to completely replace the MCUboot configuration.
This is done by creating `<sample>/sysbuild/mcuboot/` folder.
This folder will then be used as the `APPLICATION_CONFIG_DIR` when

Gerard Marull-Paretas e42f58ec94 init: s/ARCH/EARLY, call it just before arch kernel init
The `ARCH` init level was added to solve a specific problem, call init
code (SYS_INIT/devices) before `z_cstart` in the `intel_adsp` platform.
The documentation claims it runs before `z_cstart`, but this is only
true if the SoC/arch takes care of calling:

```c
z_sys_init_run_level(_SYS_INIT_LEVEL_ARCH);
```

Which is only true for `intel_adsp` nowadays. So in practice, we now
have a platform specific init level. This patch proposes to do things in
a slightly different way. First, level name is renamed to `EARLY`, to
emphasize it runs in the early stage of the boot process. Then, it is
handled by the Kernel (inside `z_cstart()` before calling
`arch_kernel_init()`). This means that any platform can now use this
level. For `intel_adsp`, there should be no changes, other than
`gcov_static_init()` will be called before (I assume this will allow to
obtain coverage for code called in EARLY?).

Fixes: #49587

Try to detect sysroot for cross-compile toolchain if not specified by
the user with `-DSYSROOT_DIR=<path>`.

First, the C compiler is asked if it knows its sysroot, some C compilers
are able to return the sysroot, as an example:
> $ arm-none-eabi-gcc -print-sysroot
> <path>/bin/../arm-none-eabi
> $

but majority of gcc-based C compilers seems to return empty string:
> $ arm-zephyr-eabi-gcc --print-sysroot
> $

in such cases, the cross-compiler target CMake file will try to discover
the sysroot by searching for libc.a, starting one level up from the
compiler location.

If no sysroot candidate is found, a warning will be printed to the user.
If a single sysroot candidate is found, this candidate will be selected.
If multiply sysroot candidates are found, a warning is printed, and the
first candiate in the list is selected. User may select another
candidate with `-DSYSROOT_DIR=<use-this>`.

CMake Error at ws/zephyr/cmake/compiler/gcc/target.cmake:25 (message):
  The only way to override its 'cc' default when cross-compiling with

github.com/Kitware/CMake/commit/f745e0497ee71d35fd1b3524b1636a72da76c266
which affects CMake 3.23.0 and 3.23.1

reverted in later releases, then it still makes sense to be able to
group compiler options together that generally are depending on each
other to function correctly.

This commit introduces the possibility to group compiler options which
must be tested together.

Usage:
> check_set_compiler_property(PROPERTY <property>

Torsten Rasmussen a5cd394758 cmake: improve warning deprecation message
The current deprecation warning could give the impression that
CROSS_COMPILE is deprecated, which is not the case.

Instead it is the behavior of defaulting to `cross-compile` when
setting CROSS_COMPILE in environment without setting
ZEPHYR_TOOLCHAIN_VARIANT that is deprecated.
Not the use of `CROSS_COMPILE` setting itself.

Stephanos Ioannidis 9d0ec5dcd6 cmake: bintools: gnu: Do not use gdb-multiarch
The commit c2419fc006 introduced a change
to the CMake toolchain detection routine in which it attempts to use
the distro-provided `gdb-multiarch` GDB executable when the target-
specific GDB executable cannot be found (i.e. fallback to
`gdb-multiarch`).

This can cause many problems for the Zephyr users because the distro-
provided GDB does not contain any Zephyr-specific patches and it may
misbehave under various conditions (e.g. negative tid/pid being
displayed, Xtensa debugging mysteriously failing, ARC debugging not
working).

This commit removes the fallback mechanism to the distro-provided
`gdb-multiarch` because it is better to display an error message saying
GDB is not found than to use a wrong GDB that can give out very
confusing and misleading error messages to users.

Moreover, this fallback mechanism is no longer necessary because the
Zephyr SDK is now available on all major host operating systems and it
provides the target-specific custom GDB that contains all Zephyr-
specific patches.

The Zephyr SDK 0.15.0 release has changed the default GDB executable to
be Python-less and introduced an alternate Python-capable variant
called `gdb-py` (note that the Zephyr SDK previously provided
`gdb-no-py` instead).

This commit updates the CMake toolchain detection routine to attempt
using the Python-capable GDB variant (gdb-py) first and, if it is not
available or fails to launch due to a missing libpython dependency,
use the Python-less GDB variant (gdb).

Torsten Rasmussen b066ae906b cmake: fix improper use of separate_arguments
The use of `separate_arguments()` in extra_flags.cmake and
unittest.cmake prevents the use of proper CMake lists.

A CMake list can be specified on command line as:
`-DMY_LIST="itemA;itemB;itemC"`

Users are expected to be able to provide extra compile flags using CMake
lists, like `-DEXTRA_CFLAGS="--flag1;--flag2"` but also using space
separated lists, like: `-DEXTRA_CFLAGS="--flag1 --flag2"`.

However, the way FLAGS was passed to separate_arguments() would result
in a list being treated as extra arguments to the function and thus
result in a CMake error.

To allow the use of CMake lists, the length of the argument as a CMake
list is tested. This ensures that when the argument contains a
single `;` then the length is >1 and no conversion is needed.

This allows a user to freely choose between the two forms:
- `-DFLAGS="--flag1 --flag2"`
- `-DFLAGS="--flag1;--flag2"`

or when passing flags which themselves contains spaces, like:
- `-DFLAGS="--flag1 \"val1 val2\""`
- `-DFLAGS="--flag1;val1 val2"`

Note that the extra escaped qouting is no longer needed for proper CMake
lists as the `;` itself informs the system that spaces are to be kept as
spaces.

Torsten Rasmussen 88ae9cbb9d cmake: extend zephyr_get() to handle build configurations from sysbuild
Enhance sysbuild controlled configurations.

The current scheme of passing settings using `-D` on the CMake
invocation is vulnerable to quoting and lists.

With `zephyr_get()` in place as a uniform way of handling user
controlled settings (CMake cache / environment / CMake local variable)
we have a mechanism in place for a cleaner handling of sysbuild
controlled settings.

This improves the robustness of variable passing and add the same cleans
up and simplifies the logic in sysbuild.

The Kconfig Zephyr CMake module has been updated accordingly so that
CONFIG settings are taken from the sysbuild shadow cache when sysbuild
is used as higher level build system.

Torsten Rasmussen 6d1f6c2d4e cmake: improved variable handling in zephyr_check_cache()
A cache variable specified by the user as `-DVAR=value` will have the
type UNINITIALIZED in the CMake cache.

Later CMake re-runs will execute the line:
set(${variable} ${CACHED_${variable}} CACHE STRING
    "Selected ${variable_text}" FORCE)

This will update the cache type from UNINITIALIZED to STRING and thus
may be picked up by other tools as a change.

To ensure the type is initialized to string, this is added:
set(${variable} ${${variable}} CACHE STRING "Selected ${variable_text}")

This code will not change the value of an existing CMake cache variable
because there is no FORCE, but what it will do is to update the cache
variable type to STRING.

As part of this, include the existing parent scope setting of variable
inside the `if(DEFINED ...)` as there is no reason to clear a variable
there is not having a value.

set(<var> ${<var>} CACHE PATH "")

if(NOT DEFINED <var>)
  set(<var> $ENV{<var>})

Torsten Rasmussen 4cb2ef83bf cmake: kconfig: preserved quotes for Kconfig string values
Fixes: #48950

Kconfig requires quoted strings in its configuration files, like this:
> CONFIG_A_STRING="foo bar"

But CMake requires expects that strings are without additional qoutes,
and therefore qoutes are stripped when loading Kconfig config filers
into CMake.

This is particular important when the string in Kconfig is a path to a
file. In this case, not stripping the quotes leads to an error as the
file cannot be found.

When users pass a string to Kconfig through CMake, they are expected to
pass it so that qoutes are correct seen from Kconfig, that is:
> cmake -DCONFIG_A_STRING=\"foo bar\"

In CMake, those qoutes are written as-is to Kconfig extra config file,
and then removed in the CMake cache.
After Kconfig processing, the Kconfig settings are read back to CMake
but without quotes. Settings that was passed through the CMake cache,
for example using `-D` are written back to the cache, but this time
without the qoutes. This results in Kconfig errors on sub-sequent CMake
runs.

Instead of writing the Kconfig value setting back to the CMake cache,
introduce an internal shadow symbol in the cache prefixed with `CLI_`.
This allows the CMake cache to keep the value correctly formatted for
Kconfig extra config creation, while at the same time keep existing
behavior for CONFIG_ symbols read from Kconfig.

Andy Ross 74cc534758 cmake: Update CONFIG_ASAN support
This had bitrotten a bit, and didn't build as shipped.  Current
libasan implementations want -fsanitize=address passed as a linker
argument too.  We have grown a "lld" linker variant that needs the
same cmake treatment as the "ld" binutils one, but never got it.  But
the various flags had been cut/pasted around to different places, with
slightly different forms.  That's really sort of a mess, as sanitizer
support was only ever support with host toolchains for native_posix
(and AFAICT no one anywhere has made this work on cross compilers in
an embedded environment).  And the separate "gcc" vs. "llvm" layers
were silly, as there has only ever been one API for this feature (from
LLVM, then picked up compatibly by gcc).

Pull this stuff out and just do it in one place in the posix arch for
simplicity.

Also recent sanitizers are trying to add instrumentation padding
around data that we use linker trickery to pack tightly
(c.f. SYS_INIT, STRUCT_SECTION_ITERABLE) and we need a way
("__noasan") to turn that off.  Actually for gcc, it was enough to
just make the records const (already true for most of them, except a
native_posix init struct), but clang apparently isn't smart enough.

Finally, add an ASAN_RECOVER kconfig that enables the use of
"halt_on_error=0" in $ASAN_OPTIONS, which continues execution past the
first error.

Torsten Rasmussen 7a65bdbd64 cmake: kconfig: introduce dedicated unit testing board
This commit introduces a dedicated unit testing board.

Today, a dedicated Zephyr unit testing scheme exists but is different
from how a Zephyr build generally works.

For example Kconfig is not possible, resulting on various different
hacks to pass Kconfig settings from test cases / testcase.yaml through
CMake to the code.
Some directly as compile definitions, some as header files with forced
inclusion on sources, some with wrapper flags which again results in
different define being enabled. There is even cases where a second
forced header inclusion undefines previous defines.

Unit test often does a manual check for the right boards, like this:
> if (NOT BOARD STREQUAL unit_testing)
>    message(FATAL_ERROR "This project can only be used with...")
> endif()

Introducing a dedicated unit_testing board under `tests/root` allows
us to use Kconfig in unit test samples, and thus proper `prj.conf` and
extra Kconfig fragments.
Generation of autoconf.h so the overall architecture follows regular
Zephyr builds.

Proper and uniform error messages when invalid board is selected.

The unit_testing board and arch is located under: `subsys/testsuite` so
that it is only available when find_package(Zephyr COMPONENTS unittest)
is used, and not available for regular Zephyr builds.

Kconfig generates autoconf.h which is applied as compile flag to
test binary which means that kconfig defines placed in ztest.h can now
be removed.

Stephanos Ioannidis 9672858c19 cmake: compiler: Add flag template for disabling strict aliasing rule
This commit adds a template for specifying the C/C++ compiler flag for
disabling the strict aliasing rule.

It also enables this flag globally because the Zephyr codebase does not
strictly adhere to the aliasing rules specified by the C/C++ standards
and the optimisation strategies that assume these rules may end up
generating invalid code.

For instance, GCC 11 and above tend to optimise more aggressively
assuming the strict adherence to the standard aliasing rules and may
generate invalid code, when compiling Zephyr with `-fstrict-aliasing`,
that results in various run-time failures.

Note that the footprint and performance ramifications of disabling the
strict aliasing rule are negligible.

Yuval Peress 84dfb8edf8 ztest: allow asserts anywhere
Updates the ztest_test_fail() function to allow failures in setup.
When executed, a failed assert will fail every test in the suite owning
the setup function. This was verified by adding a suite which asserts
in the setup function and has a test that should pass. During
exeuction, ztest marks the test as failing.

In order to verify exection I also added 2 new APIs:
- ZTEST_EXPECT_FAIL(suite_name, test_name)
- ZTEST_EXPECT_SKIP(suite_name, test_name)

Nicholas Lowell 3da90ad21f cmake: use all compile options arguments for uniqueness
zephyr_library_compile_options() was attempting to create
unique hashes for compile options in order to prevent creating
them multiple times.  However, it was only using the first
argument to create the hash, so if multiple libraries had
different compile options but the first line was the same,
the second set would be mistaken for the first set and would
actually be passed the first set during compilation instead
of its own set.

The fix should be to use the entire compile options argument
list to create the hash so they should only match if the entire
options list is exactly the same.

This is a continued fix for #43835

Nathan Krueger 6a5520c626 arch/riscv: Adding KConfig options for 'A' and 'M' RISC-V extensions
New KConfig options for 'A' and 'M' RISC-V extensions have been
added.  These are used to configure the '-march' string used by GCC
to produce a compatible binary for the requested RISC-V variant.
In order to maintain compatibility with all currently defined SoC,
default the options for HW mul / Atomics support to 'y', but allow
them to be overridden for any SoC which does not support these.

I tested this change locally via twister agaisnt a few RISC-V platforms
including some 32bit and 64bit. To verify the 4 possibilities of Atomics
& HW Mul: (No, No), (No, Yes), (Yes, No), (Yes, Yes -- current behavior),
I used an out-of-tree GCC (xPack RISC-V GCC) which has multilib support
for rv32i, rv32ia, rv32ima to test against our out-of-tree Intel Nios V/m
processor in HW.  The Zephyr SDK RISCV GCC currently does not contain
multilib support for all variants exposed by these new KConfig options.

David Leach c243da02ed code_relocation: Move NOCOPY flag to avoid OS drive colon
COPY/NOCOPY flag was added to the end of the string with ':'
as separators. The python script then split the line on ':'
which breaks on Windows build because the string was

[MEM]:[FILE]:[COPY]

In windows you will have 'c:\' in the file path so the
line.split() in script will split on the 'c:'.

Move the COPY/NOCOPY to:

[MEM]:[COPY/NOCOPY]:[FILE]

Note that the comments at top of gen_relocate_app.py also
indicates this format.

Currently when a node has a 'zephyr,memory-region' compatible and a
'zephyr,memory-region' string property, a new memory region is created
in the linker script.

Having a memory region without a section to place variables in could be
not that useful. With this patch we extend the memory-region mechanism
to also create sections.

The user can then place variables in the sections as usual by using for

Torsten Rasmussen f96ee77c7c cmake: function to update Zephyr_DIR when loading old Zephyr packages
Fixes: #43094

This commit introduces a function which updates Zephyr_DIR to point to
the directory of the Zephyr package being loaded.

For Zephyr 3.0 and earlier, the Zephyr_DIR might in some cases be
`Zephyr_DIR-NOTFOUND` or pointing to the Zephyr package including the
boilerplate code instead of the Zephyr package of the included
boilerplate code.

This code ensures that when a package is loaded then Zephyr_DIR will
point correctly.
This ensures that when Zephyr releases <=3.0 is loaded, then Zephyr_DIR
will point correctly, see more in #43094.

Old style Zephyr package will in some cases load boilerplate.cmake
directly so to ensure proper behavior, restrict boilerplate uses of
`find_package(Zephyr)` to not use default search path, but allow only
the current Zephyr.

Of the same reason, only print warning if Zephyr_DIR is not defined as
this indicates old style inclusion.

Torsten Rasmussen 8b199b0fbb cmake: test CMake and issue error if using 3.22.1 / 3.22.2 from PyPI
Fixes: #43099

The CMake 3.22.1 / 3.22.2 PyPI version suffers a bug in the
`cmake_path(... PARENT_PATH)` implementation.

Therefore, when CMake version 3.22.1 / 3.22.2 is detected, test if the
CMake version is suffering from the bug, and in case the bug is present,
fail with an error regarding the issue.

The reason for failing, and not implementing work arounds is that Zephyr
already uses `cmake_path()` at two locations, and we cannot prevent
contributors from adding code which uses this function.

Secondly, Zephyr modules may also use `cmake_path()`, and thus be
affected by said bug.
It is impractical to implement work arounds at all possible locations
for something that is a CMake bug.

Therefore the safest solution is to test CMake itself, to check if the
version in use suffers said bug, and fail with a proper error message
if an affected CMake version is used.

Initially, the new toolchain simply includes files from current xcc

approach to diverge the toolchains in the future than placing
"if($ENV{XCC_USE_CLANG})" at several places.

It should also help to filter tests that run (or not) exclusively with
the clang variant of XCC on twister.

The XCC_USE_CLANG flag is documented as deprecated, and a message is
emitted during build if still in use. Its new behaviour is to instruct

Torsten Rasmussen 117008331d cmake: package_helper CMake script
The Zephyr CMake package helper script allows to invoke Zephyr package
modules as they are invoked at configure time, up to the modules given
with `-DMODULES=<modules>`.
This allows to run the configure time part of the Zephyr build system
without generating a complete build system.

This means that for example devicetree module can be invoked for a given
sample and board to generate zephyr.dts identical to what is created
by the build system during a build.

To generate zephyr.dts for hello_world, invoke the script as:
$ cmake -DBOARD=<board> -B build -S samples/hello_world \
$       -DMODULES=dts -P <ZEPHYR_BASE>/cmake/package_helper.cmake

Other modules, for example 'kconfig' and 'zephyr_modules' can also be
invoked this way.

This will allow other tools, such as twister, to executed only a
subset of the build system like dts in order to do filtering before
determine if a complete build should be invoked.

Create a cmake/modules folder containing all Zephyr CMake modules.
All Zephyr cmake files that are included from boilerplate are now
converted into CMake modules which can be individually loaded.

The Zephyr CMake package is updated to support loading of individual
CMake modules using the COMPONENTS argument to `find_package(Zephyr)`.
If the COMPONENTS argument is not specified, the default Zephyr build
system will load.
If COMPONENTS is specified then, only those components and the
dependencies will be loaded.

If a Zephyr CMake module depends on another CMake module which has not
been loaded, it will automatically be loaded.

This allows us to modularize and reuse individual parts of the Zephyr
CMake build system in a more flexible way in future.

Such usage could be:
- Higher livel multi image build system
- Invocation of individual components, for example dts processing by
  twister without loading all build code
- Doc build
- Unittesting

Carlo Caione d3203dc70d code_relocation: Add NOCOPY feature
* Use case of interest:

Some platforms are shipping in parallel to the internal FLASH some other
storage / external FLASH (usually a QSPI FLASH) that can be used to
execute (XIP) code from.

The content of this external FLASH can usually be written at flash time
using proper tools (see for example the case of the external FLASH on
the nRF5340DK that can be written at flash time using nrfjprog).

The external FLASH is a nice addition that is extremely useful when a
large application code doesn't entirely fit on the internal FLASH so
that we could want to move part of it in the auxiliary FLASH to XIP the
code from there.

* The problem:

Right now Zephyr doesn't have a formal and generic way to move at build
time part of the code to a different memory region.

* The current status:

Zephyr is indeed shipping a code_relocation feature but that doesn't
entirely match our needs.

When XIP is enabled, the code_relocation feature is used in Zephyr to
move the selected code (that is to copy text section, to initialize data
and zero bss) from FLASH to SRAM at run time and execute code from SRAM.

The relocation is done by a generated snippet of code that is
memcpy()-ing the right content to the destination region also using some
build-time generated portions of linker script to retrieve start and
destination addresses and regions.

* This patch:

This patch is leveraging the code_relocation code and adding a NOCOPY
feature. This feature is using the code_relocation feature to
dynamically build the linker script snippets but entirely skipping the
run-time code relocation so that the code can be XIP-ed from the
destination region.

* Example:

Let's say that we have a big file called `huge_file.c` that we want to
XIP from the external FLASH that is mapped in an EXTFLASH region.

In this case we should enable `CONFIG_XIP` and
`CONFIG_CODE_DATA_RELOCATION` and instruct cmake as follows:

  zephyr_code_relocate(src/huge_file.c EXTFLASH_TEXT NOCOPY)
  zephyr_code_relocate(src/huge_file.c SRAM_DATA)

this means that:

- The .text section of the `huge_file.c` must reside in the EXTFLASH
  memory region and we do not need to copy the section there because we
  are going to XIP it (and we assume that the file is going to be placed
  in the external FLASH at flash time).
- The .data section of the `huge_file.c` must still reside in the SRAM
  memory region.

* TODOs:

It's desirable to have the possibility to relocate libraries and
pre-build files instead of source code files.

Nicolas Pitre 678b76e4b0 kernel/init.c: allow for memset/memcpy alternatives during early boot
Zeroing the BSS and copying data to RAM with regular memset/memcpy may
cause problems when those functions are assuming a fully initialized
system for their optimizations to work e.g. some instructions require
an active MMU, but turning the MMU on needs the .bss section to be
cleared first, etc.

Commit c5b898743a ("aarch64: Fix alignment fault on z_bss_zero()")
provides a detailed explanation of such a case.

Replacing z_bss_zero() with an architecture specific one is problematic
as the former may see new sections added to it that would be missed by
the later. The same reasoning goes for z_data_copy().

Let's make maintenance much easier by providing weak versions of
memset/memcpy that can be overridden by architecture-specific safe
versions when needed.

Torsten Rasmussen ea082ac2c9 cmake: only write devicetree files when there are changes.
As part of #40167 is was discovered that devicetree headers are always
generated when CMake re-runs.

This causes all source files that directly or indirectly through
included headers to recompile when CMake re-runs, even if there are no
changes to devicetree.

This commits introduces `zephyr_file_copy(...)` similar to
`file(COPY_FILE ...)` from CMake 3.21.
However, as CMake 3.20 is supported by Zephyr we need a zephyr variant
of this function to allow usage with CMake 3.20.

This ensures that only when there are changes to devicetree headers,
then source files will recompile.

Torsten Rasmussen 91709778a4 cmake: version.h generation performed at build time
Fixes: #39503
Fixes: #40167

This commit moves `BUILD_VERSION` CMake variable from a compile
definition to be a define inside version.h.

Besides the benefit of having related settings grouped in a common
header, it also means that an updated `BUILD_VERSION` value does not
need to trigger re-compilation of all source files.

When using compile definitions, CMake cannot tell whether a given source
files uses the definition or not, and hence all sources must be
recompiled to be sure they are up-to-date.

Placing `BUILD_VERSION` in version.h, the source dependencies ensures
that only source files including `version.h` gets recompiled.

As part of this, version.h generation is moved so that it is now done
at build time.
This means that re-generation of version.h is no longer depending on a
CMake re-run but can have it's own dependency in `.git/index` when git
described is used to obtain `BUILD_VERSION` information.

Generation of logging dictionary database has been updated to support
BUILD_VERSION from header file instead of CMake configure time variable.

Daniel Leung 83939c267c cmake: force assembler ID to be GNU for GCC-based XCC
GCC-based XCC uses GNU Assembler (xt-as). However, CMake doesn't
recognize it when invoking through xt-xcc. This results in CMake
going through all possible combinations of command line arguments
while invoking xt-xcc to determine assembler vendor. This multiple
invocation of xt-xcc unnecessarily lengthens the CMake phase of
build, especially when XCC needs to obtain license information
from remote licensing servers. So here forces the assembler ID
to be GNU to speed things up a bit.

Daniel Leung 0b09ca8cd0 cmake: compiler/xcc: override and clear debug property for clang
Some older versions of XCC Clang would result in the following
error during compilation:

  /tmp/file.s: Assembler messages:
  /tmp/file.s:20: Error: file number 1 already allocated
  clang-3.9: error: Xtensa-as command failed with exit code 1

due to a bug in LLVM: https://bugs.llvm.org/show_bug.cgi?id=11740.
This is fixed in upstream, https://reviews.llvm.org/D20002, in 2016.
However, it seems that it is only fixed after XCC RI-2018.0.
Instead of blanket disabling usage of '-g', use an environment
variable "XCC_NO_G_FLAG" to disable usage of flag '-g' to workaround
this issue. This needs to be manually set because there is no way to
know which XCC version is being used, and compiler flag checking for
'-g' would not result in error (and thus '-g' is not ignored).
This is only needed for older XCC Clang. For sufficiently new XCC
verisons, there is no need for this.

Note that this is an alternative implementation to commit
deeb98da53. This one does not
alter the GCC flag file, and instead, simply clear the debug
compiler property so "-g" is not used.

This is useful when the image is to be flashed at a location different

An example use-case is multicore systems where core A might load image
from a flash partition into RAM in order for core B to execute and load,
but where the image itself is build with the RAM addresses as LMA.

It updates the zephyr_image_info.h header with information of adjustment

Martí Bolívar 2b7c61e306 cmake: re-work devicetree preprocessing steps
This causes any devicetree error messages to refer to the source files
which contain the errors instead of intermediate <BOARD>.dts.pre.tmp
files in the build directory.

Do this using a new python-devicetree feature which can correctly
handle cpp's generated line marker directives.

To use this feature, rework the way that the C preprocessor is run on
devicetree inputs so that line marker directives are preserved by
removing the -P option.

This is a backwards incompatible change to the way the generated files
in the build directory used to work, as not all tools can consume line
markers. In particular, dtc can't handle these lines. We therefore
pass dtc zephyr.dts instead (the final parsed devicetree output from
python-devicetree).

Since <BOARD>.dts.pre.tmp is a publicly documented file, this is
changing existing behavior, so use a new file name for the
intermediate files to make it more obvious that something changed. In
particular, use zephyr.dts.pre instead of <BOARD>.dts.pre.tmp.
(The $BOARD.dts.pre.tmp name is a little cumbersome anyway.)

dtc, because it runs before gen_defines.py. This means that any
improvements we make to devicetree error handling and reporting in
dtlib or edtlib will never be noticed by users that have dtc
installed.

(This also has the unfortunate effect of hiding dtlib error reporting
from me, since my systems all have dtc installed.)

Move dtc to after gen_defines.py, so that initial error handling and
warnings all come from python. If DTC has some additional warnings or
errors to report, let them come last. They will still halt the build
if anything is wrong.

Martí Bolívar 8346032d19 cmake: extensions: improve DT consistency with python APIs
In the python APIs we use for devicetree, you can generally use an
alias interchangeably with the full path to a node.

For example, dtlib.py says:

    [...] both dt.get_node("/foo/bar") and dt.get_node("bar-alias")
    will return the 'bar' node below:

      /dts-v1/;

      / {
              foo {
                      bar_label: bar {
                              baz {
                              };
                      };
              };

              aliases {
                      bar-alias = &bar-label;
              };
      };

    Fetching subnodes via aliases is supported:
    dt.get_node("bar-alias/baz") returns the 'baz' node.

Now that we have the necessary helper functions for resolving alias
names, make the CMake APIs to devicetree behave the same way. This
improves consistency between the two sets of devicetree helpers used
by the build system, making them both match the general devicetree
practice that an alias is as good as a path. This is good for
consistency.

Jordan Yates 28b2e55321 cmake: rework linker script generation and linker prebuilt stages
This commit reworks the linker script generation and linking stages in
order to better support fixed section location as required by #38836.

Today we have the following generated linker scripts and the elf output
depending on the system configuration:
- linker_app_smem_unaligned.cmd --> app_smem_unaligned_prebuilt.elf
- linker_zephyr_prebuilt.cmd    --> zephyr_prebuilt.elf
- linker.cmd                    --> zephyr.elf

as not all linker scripts may be created and as there is a need for the
possibility to move gen handles earlier then those stages has been
renamed into more generic names so that with this commit we have:
- linker_zephyr_pre0.cmd --> zephyr_pre0.elf
- linker_zephyr_pre1.cmd --> zephyr_pre1.elf
- linker.cmd             --> zephyr.elf

This also means that is the stage zephyr_pre1 is not needed, then build
can go from `zephyr_pre0.elf` to `zephyr.elf`.

The gen_handles.py has been changed so it now uses `zephyr_pre0.elf` as
input. This ensures that the handles array are final when invoking the
next build and linking stages.

To keep the current behavior of generating the isr table and kobj hash
of what was `zephyr_prebuilt` stage the code blocks contolling isr
generation and kobj hash has been relocated to be located after
app_smem and device handle generation.

Torsten Rasmussen fffaf05e5d scripts: support for build meta file creation
This commit is motivated by the west discussion in:
https://github.com/zephyrproject-rtos/west/issues/548

The commit provides the ability to generate a build meta info file
containing lists of:
- Zephyr:         path and revision
- Zephyr modules: name, path, and revision
- West:           manifest path
                  path and revision for each project

For Zephyr or Zephyr modules the revision will be `null` if it is not
under git version control.

If Zephyr, a modules, or a project has uncommitted changes, the revision
will be marked dirty.

If west is not installed or used for the build process, the
west-projects list will be empty.

If a project is both a Zephyr module and a west project it will show up
in both lists.

Similar to Zephyr, which is independently referred as the Zephyr in use
but also listed as west project when west is used.
This is important in case ZEPHYR_BASE was manually set and pointing to
a different Zephyr repository.

The build meta file is not created per default but can be enabled with
the BUILD_OUTPUT_META Kconfig setting.

A project using west and having an extra Zephyr module loaded not
controlled using git can look like:
zephyr:
  path: /.../zephyr
  revision: 863600cd0e3c0a271e86629c5089821e5e4380cc-dirty
modules:

  revision: null
west:

Torsten Rasmussen 1198087440 cmake: APPLICATION_CONFIG_DIR support implemented
With this commit a dedicated APPLICATION_CONFIG_DIR is added to the
Zephyr build system.

Currently, the APPLICATION_SOURCE_DIR is identical also the base
location of configuration files.

This is very practical for simple samples, but also has it limitations
for more complex setups.

Introducing a dedicated APPLICATION_CONFIG_DIR allows users more
customization options in Zephyr build system.
Especially in terms of custom build configuration files unknown to
Zephyr itself.

For example, instead of all configuration files being located directly
in the application source folder, a project might prefer to organize
their configuration files on a per board basis, for example:
<app>/boards/custom_board_A/prj.conf
<app>/boards/custom_board_A/app.overlay
<app>/boards/custom_board_A/custom_file.mine
<app>/boards/custom_board_B/prj.conf
<app>/boards/custom_board_B/app.overlay
<app>/boards/custom_board_B/custom_file.mine
...

instead of n-files located in the root of the sample.

If the user / sample specifies APPLICATION_CONFIG_DIR, then this folder
will always be used instead of the default configuration folder.

As part of this extension the behaviour of
`-DCONF_FILE=<relative-path>/prj_<build>.conf` and additional Kconfig
fragments automatic sourcing has been aligned with the default behavior
of `prj.conf`.

Torsten Rasmussen 2eb13159ec cmake: kconfig: use absolute files for merge_config_files
The `merge_config_files` list contains files with both relative and
absolute paths.
Each entry is checked and files with a relative path are converted to
absolute path. This creates a `merge_config_files_with_absolute_paths`
identical to the `merge_config_files` but with absolute path on each
entry.

Afterwards it is mixed whether `merge_config_files` or
`merge_config_files_with_absolute_paths` are used creating unnecessary
risk when the list with relative path files are used.

This commit sets the content of `merge_config_files` with updated
absolute paths files, and also updates all places to use this list.

This ensures that after path conversion then only the list with absolute
paths is used.

Torsten Rasmussen 9c74027a7b cmake: CMake linker script generator pass handling
To prepare for linker script creation with flexible number of linker
passes depending on system configuration then the Zephyr CMake linker
script generator has been updated to use pass names instead of pass
numbers.

This allows greater flexibility as a section can now be active based on
the settings on the pass and not the linking pass index number.

As part of this, the `PASS` processing in `linker_script_common.cmake`
has been adjusted so that it properly handles when a linking pass is
handling multiple settings, such as both `LINKER_APP_SMEM_UNALIGNED`
and `DEVICE_HANDLES_PASS1` in same linking pass.

As the number of linking passes are more flexible, then the PASS
argument in `zephyr_linker_section()` and
`zephyr_linker_section_configure()` has been updated to also support
a `NOT <name>` argument, for example: `PASS NOT LINKER_ZEPHYR_FINAL`.

Torsten Rasmussen 1fa3f15137 cmake: update configure_linker_script() to prepend -D on defines
Currently all calls to `configure_linker_script()` specifies `-D<name>`
when calling `configure_linker_script()`.

This works well for the gcc pre-processed ld linker script templates,
but Zephyr also supports a CMake linker script generator which can be
used for ld scripts and armlink scatter files.

In this case, a `-D` must be stripped.

This commit changes this so that Zephyr CMake build system calls
`configure_linker_script()` without `-D`.
Thus the `LINKER_SCRIPT` choice can decide how this information should
be passed to underlying linker script functionality, that is `-D` for
linker script template and CMake variable for the CMake linker script
generator.

Immo Birnbaum f4d41b1a6c cmake: boards: make QEMU icount sleep parameter configurable
When QEMU is running in icount mode, the behaviour regarding
the CPU being in sleep mode is configurable, with the default
value being set to 'off'. In this case, instruction counting
continues even when the CPU is sleeping or no target time is
set in the system timer. If the sleep parameter is set to
'on', instruction counting stops if the CPU is sleeping, and
the instruction count will fast-forward directly to the next
target time once it is being set.

In the Xilinx derivative of QEMU (which simulates ZynqMP and
Zynq-7000 SoCs), the default configuration causes QEMU to no
longer accept control commands via the console or remotely
whenever Zephyr enters and remains in idle mode.

Therefore, this commit makes the value of the sleep para-
meter of the icount functionality configurable, with the
default value remaining 'off'. The value can be changed at
board level alongside with the specification of the icount
shift value.

Torsten Rasmussen 917d5021d7 cmake: CMake compile features support
Fixes: #36558 #32577

This commit introduces CMAKE_C_COMPILE_FEATURES and
CMAKE_CXX_COMPILE_FEATURES.

This allows users to use the `target_compile_features()` in their own
code.

In Zephyr, the CMAKE_C/CXX_COMPILE_FEATURES are defined based on the
compiler and the Kconfig / CSTD setting.
Doing so ensures that a user compiling Zephyr with c99 and specifies
`target_compile_features(<target> ... c_std_11)` will get an error.
And similar if building Zephyr with C++ support and c++11, but testing
for `target_compile_features(<target> ... cxx_std_17)`.

For example in the C++ case, the user must ensure that Zephyr is
compiled with C++17, that is: CPLUSPLUS=y and STD_CPP17=y, in which case
the CMAKE_CXX_COMPILE_FEATURES will contain support for C++17 and thus
the `target_compile_features(<target> ... cxx_std_17)` will succeed.

Carles Cufi 76c4591e6b cmake: gnu: Fix debugging when GDB fails to load because of Python
GDB can be built with or without Python support. When built with Python
support this can cause a particular problem: The gdb executable relies
on shared libraries that are bound to a specific Python version. But
since most Linux distributions typically ship with a single version, it
is very difficult to choose which one to target when building GDB.
When GDB executes, if it fails to load the shared libraries it will exit
immediately with an error code of 127 and output resembling this:

/home/carles/bin/zephyr-sdk/arm-zephyr-eabi/bin/arm-zephyr-eabi-gdb:
error while loading shared libraries: libpython3.8.so.1.0: cannot open
shared object file: No such file or directory

There are two known approaches to shipping multiple gdb executables:

- The Zephyr SDK ships a default gdb with Python enabled, and then a
  separate gdb-no-py executable with Python disabled
- GNU Arm Embedded ships with a default gdb with Python disabled, and an
  additional gdb-py with Python enabled

To mitigate the problem of not being able to debug, fall back to a
'gdb-no-py' if it exists whenever the standard gdb executable fails to
even run.

Fixes: #37637

toolchain_parse_make_rule() parses depfiles and converted `\\` to the

However, gcc -M might create depfiles with windows path separator `\`

resulting in a file list as:
c:;...;zephyr;samples;drivers;led_ws2812;nrf52-bindings.h

which results in a CMake configure dependency to be added to `C:`.
As C: is always newer than the build.ninja file, this resulted in
continues CMake re-invocation.

As a small side-note, the `\` in file name did only occur in situations
where a relative past had been used elsewhere in the build system, such
as here:

As a first common property is the `ALLOW_EMPTY` property which allows

Stephanos Ioannidis 41fd6e003c arch: arm: aarch32: Add half-precision floating-point configs
This commit adds the half-precision (16-bit) floating-point
configurations to the ARM AArch32 architectures.

Enabling CONFIG_FP16 has the effect of specifying `-mfp16-format`
option (in case of GCC) which allows using the half-precision floating
point types such as `__fp16` and `_Float16`.

Note that this configuration can be used regardless of whether a
hardware FPU is available or supports half-precision operations.

When an FP16-capable FPU is not available, the compiler will
automatically provide the software emulations.

Torsten Rasmussen 36bb00d1f5 armclang: ARM Compiler C library support
Support for ARM Compiler C library.

This commit add support for the ARM Compiler C libary in:
- Kconfig
- libc/armstdc

A new Kconfig symbol is added to allow a toolchain to specify if they
support linking with the minimal C library.
Also the CMake variable `TOOLCHAIN_HAS_NEWLIB` is exported to Kconfig
so that CONFIG_NEWLIB_LIBS can only be enabled if the toolchain has
newlib.

The armclang toolchain selects the CMake scatter file generator and
disables support for the LD linker template which is not supported by
armlink.

For the ARM Compiler C library, a corresponding lib/libc/armstc/ folder
with a minimal implementation to work with the ARM Compiler C library
is added.

Torsten Rasmussen 28ba86d066 armclang: armlinker: armlink symbol steering file
This commit introduces armlink steering file.

A steering file in armlink allows Zephyr to keep using existing linker
symbols defined in ld scripts and used throughout the code tree.

The steering file is generated at build time in order to resolve Zephyr
linker symbols to their corresponding armlink symbols.

As example, Zephyr defines __ramfunc_start which corresponds to the
armlink auto defined Image$$ramfunc$$Base symbol.

Or __init_PRE_KERNEL_1_start which corresponds to Image$$init_0$$Base.

Torsten Rasmussen 93f0d0d528 armclang: warn on non-Ninja generator for CMake 3.20.
When using ARMClang linker and scatter files (armlink) then all
libraries are linked as object libraries using `$<TARGET_OBJECTS:lib>`.

CMake version 3.20 only has limited support for such linking:
> Referencing $<TARGET_OBJECTS> in target_link_libraries calls worked
> in versions of CMake prior to 3.21 for some cases, but was not fully
> supported.

One of those cases that do not work is Unix Makefiles generators.

As only Ninja is currently verified to work, this commit will check the
CMake version in use and the generator, and if CMake version <=3.21 is
used with non-Ninja generator then an error is raised informing user
to either use Ninja generator or update CMake.

As the Ninja generator has been confirmed to work as expected, then that
generator is accepted with CMake 3.20 and older.

Torsten Rasmussen c9804d24fe scripts: gen_handles.py: take device start symbol as argument.
The current gen_handles.py script uses linker defined symbols.
As preparation for support of more linkers the gen_tables.py now takes
the device start symbol as argument.

For example, armlink and ld uses different symbols.
With ld those can be named explicitly, but for armlink the linker
decides the names.

For ld, Zephyr defines: __device_start
For armlink, the symbol is defined as: Image$$<section name>$$Base

Therefore knowledge of the linker symbol to be used must be passed to
gen_handles.py so that the correct symbol can be used for locating
devices.

To support this change, the creation of the asm, compiler, compiler-cpp,
linker targets has been moved from target_toolchain_flags.cmake to
target_toolchain.cmake.

All linkers has been updated to support the use of the
device_start_symbol on the linker target.

List of linkers updated:
- ld
- lld
- arcmwdt

Stephanos Ioannidis 6df8f7e435 arch: arm: cortex_m: Add ARMv8.1-M MVE configs
This commit adds the ARMv8.1-M M-Profile Vector Extension (MVE)
configurations as well as the compiler flags to enable it.

The M-Profile Vector Extension consists of the MVE-I and MVE-F
instruction sets which are integer and floating-point vector
instruction sets, respectively.

The MVE-I instruction set is a superset of the ARM DSP instruction
set (ARMv7E-M) and therefore depends on ARMV8_M_DSP, and the MVE-F
instruction set is a superset of the ARM MVE-I instruction set and
therefore depends on ARMV8_1_M_MVEI.

The SoCs that implement the MVE instruction set should select the
following configurations:

  select ARMV8_M_DSP
  select ARMV8_1_M_MVEI
  select ARMV8_1_M_MVEF (if floating-point MVE is supported)

The GCC compiler flags for the MVE instruction set are specified
through the `-mcpu` flag.

In case of the Cortex-M55 (the only supported processor type for
ARMv8.1-M at the time of writing), the `-mcpu=cortex-m55` flag, by
default, enables all the supported extensions which are DSP, MVE-I and
MVE-F.

The extensions that are not supported can be specified by appending
`+no(ext)` to the `-mcpu=cortex-m55` flag:

  -mcpu=cortex-m55           Cortex-M55 with DSP + MVE-I + MVE-F
  -mcpu=cortex-m55+nomve.fp  Cortex-M55 with DSP + MVE-I
  -mcpu=cortex-m55+nomve     Cortex-M55 with DSP
  -mcpu=cortex-m55+nodsp     Cortex-M55 without any extensions

Marc Herbert 654a2f245d git.cmake: print BUILD_VERSION always, simplify and fix error message
In an ideal world, good CIs make it very clear what exact git versions
are getting built. However:

- Zephyr is (re-)used in many projects and they cannot all be expected
  to have ideal CI.

- CI with multiple git repos is complex (#34713) which makes the world
  an even less ideal place: much more chance for some git versions to be
  missing.

- Many developers don't realize that Github and other CIs do not test
  pull/12345/head but the moving target pull/12345/merge instead. While
  not resolving pull/12345/merge completely (maybe another day), this
  commit provides at least evidence that pull/12345/head is NOT the
  commit tested.

So the addition of the following line in the logs is a very small price
to pay that can save enormous amounts of time when trying to understand
some obscure build failures.

-- BUILD_VERSION=zephyr-v2.5.0-2957-g6230b5bb66bc

Note this obviously does not provide any git information when
BUILD_VERSION is overriden but it does not hurt either in this case:
knowing BUILD_VERSION was overriden is also useful.

The "BUILD_VERSION is left undefined" message was just wrong in
the (unlikely) case `git describe` printed something while also
failing. Remove it; it's so much simpler to just print $BUILD_VERSION
and give the direct, unfiltered information.

Note this simplification is also a partial revert of 1b80f00f56
which threw the entire git warnings "baby" with some obscure duplicate
1.13.0 "bathwater" that is not relevant any more and that I guess barely
anyone noticed even at the time.

Torsten Rasmussen 3dd65a7663 runners: remove dependencies from runners
Today, there is a build target is added for each runner: flash, debug,
debugserver, attach.

And those runners will have a dependency to Zephyr logical target that
is built before invoking `west <runner>`.

This design has some flaws, mainly that additional dependencies directly
on the target will not be built when running `west <runner>` directly.
That generator expressions cannot be used for the DEPENDS argument.

Instead, the build target `<runner>` will not have any dependencies, and
will raise a build error if a dependency is added to the target.
Due to how `add_dependencies()` work, this must be done as a build time
check, and not configure time check.

`west <runner>` will invoke a build before executing the runner, and
this way ensure the build target is up-to-date, which again removes the
need for a dedicated `west_<runner>_target`.

It also minimizes the risk of developer errors, as developers no longer
need to consider the need for adding additional dependencies.
If a custom target is part of the default `all` build, then it's ensured
to be up-to-date.
