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

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.

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.

Instead of setting XCC_USE_CLANG=1, this patch adds xcc-clang toolchain
that is basically xcc using the clang compiler.
Initially, the new toolchain simply includes files from current xcc
toolchain and (re)sets some variables. This should be a more scalable
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
Zephyr to use `xcc-clang` toolchain.

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

* 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.

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.

As part of #40167 is was discovered that devicetree headers are always

This commits introduces `zephyr_file_copy(...)` similar to

However, as CMake 3.20 is supported by Zephyr we need a zephyr variant

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.

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

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

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

However, the $ must only be escaped in Linux and MacOS, not on windows

CMP0002 was introduced in CMake 2.6 and was set to NEW.

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.)

Curently, any and all devicetree syntax errors are being handled by
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

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.
Signed-off-by: Martí Bolívar <marti.bolivar@nordicsemi.no>
This is a helper function for looking up the path to a devicetree

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

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:

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`.

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

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

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`.

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.

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.

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.

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

When GDB executes, if it fails to load the shared libraries it will exit

- 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.

This commit removes: `cmake_policy(SET CMP0079 OLD)`
This means Zephyr will now allow the new CMP0079 behavior introduced
with CMake version 3.13.
Code has now been examined and no occurences has been found where the
INTERFACE keyword was used with `target_link_libraries()` outside the
CMakeLists.txt scope where the original libraries were created.
As an additional safeguard `./scripts/twister -c -N --cmake-only`
has been executed before and after this change and all `build.ninja`
files for each test / sample have been diffed.
Removing the CMP0079 policy creates identical build files, hence removal
of the old policy will not impact the build.

toolchain_parse_make_rule() parses depfiles and converted `\\` to the
CMake list separator `;`.
However, gcc -M might create depfiles with windows path separator `\`
causing this conversion to fail, as a path like:
c:\...\zephyr\samples\drivers\led_ws2812\nrf52-bindings.h
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:
https://github.com/zephyrproject-rtos/zephyr/blob/\

This introduces a dedicated zephyr_library_property() function which
provides a common way to set Zephyr build system known properties on
Zephyr libraries.
As a first common property is the `ALLOW_EMPTY` property which allows
to create a `zephyr_library()` without putting any content inside of it.
In general libraries should not be created unless there are files to
places inside of it, however in some cases there are so many
`zephyr_library_sources_ifdef(<setting> <file.c>)`
where testing each setting before creating the library may not be
desired.
This commit allows the following construct in those cases:
```
zephyr_library()
zephyr_library_property(ALLOW_EMPTY TRUE)
zephyr_library_sources_ifdef(CONFIG_SETTING_1 file_1.c)
zephyr_library_sources_ifdef(CONFIG_SETTING_2 file_2.c)

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.

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

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.

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.

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.

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

As Zephyr still supports the use of CMake 3.13, and the current use of
DEPFILE in linker/ld/target.cmake is already absolute path, then the
safest choice is to use old behavior.
This can be changed when Zephyr increases minimum required CMake to be
3.20 or newer.

Always source the Zephyr base soc and shield (board root) Kconfigs
directly from Kconfig instead of generated Kconfig files.
This has the benefit that it is no longer necessary to generate Kconfig
files to source SoC root and shield (board root) when no custom roots
are provided.
Also this cleans up the doc/CMakeLists.txt and ensures that the
doc/CMakeLists.txt is not getting out of sync with the Kconfig.cmake.

The current implementation of Zephyr build configuration CMake package
only allows the build configuration package to be placed inside a
Zephyr workspace.
This commit extends the usability by allowing users to locate the
Zephyr build configuration CMake package outside the Zephyr workspace
and then refer to the package using
`-DZephyrBuildConfiguration_ROOT=<path>`
`set(ZephyrBuildConfiguration_ROOT <path>)`
This allows users greater flexibility in their workspace layouts.

If user is specifying `-DBUILD_VERSION=<value>` then the proper way to
test is using `NOT DEFINED BUILD_VERSION`.
The difference between `NOT DEFINED BUILD_VERSION` and
`NOT BUILD_VERSION` is that a user specifying `-DBUILD_VERSION=0` will
result in `NOT BUILD_VERSION` becoming true, whereas
`NOT DEFINED BUILD_VERSION` would be false, which is the correct
behavior here, as the user actually provided a specific BUILD_VERSION.

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.

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.

`west` is an optional tool.
Although `west` is optional, a developer might be working with both west
and non-west based projects, like
- vanilla Zephyr (using west)
- downstream project (not using west)
and thus have west installed, but not always in use.
In the downstream project scenario not using west, then running CMake
will print the following error:
```
FATAL ERROR: no west workspace found from "<path>/zephyr";
"west topdir" requires one.
Things to try:
- Change directory to somewhere inside a west workspace and retry.
- Set ZEPHYR_BASE to a zephyr repository path in a west workspace.
- Run "west init" to set up a workspace here.
- Run "west init -h" for additional information.

This commit sets `WEST` CMake variable to `WEST-NOTFOUND` when west is
found but Zephyr is not in a west workspace (`west topdir` fails)

With the introduction of #32556 changing the BOARD now prints a warning.
Zephyr provides `zephyr_file()` to look up overlays and Kconfig
fragments for a specified board, and it used to be possible and safe to
do:
```
function(my_func)
set(BOARD <local_scope_board>)
zephyr_file(CONF_FILES ...)
endfunction(my_func)
```
As the BOARD inside `my_func` is locally scoped, this is safe to do.
But with introduction of #32556 a warning is now printed when running
CMake.
Therefore `zephyr_file` has been extended to allow for optional BOARD
and BOARD_REVISION arguments.
If BOARD is not given as argument the current BOARD in the build system
will be used.

Watching of specific Zephyr CMake build variables ensure users cannot
accidentally set important variables, such as BOARD, SHIELD, CONF_FILES
late in the build process.
This was also added to zephyr_check_cache() function.
However, the BOARD provided by the user may look as `<board>@<revision>`
and will be kept in the cache in that form.
However, the BOARD value from cache is spit into internal build
variables as: BOARD=<board> and BOARD_REVISION=<revision>.
However, this is done after `zephyr_check_cache()` which then triggers
the variable watch to trigger, and printing a warning when using board
revisions.
Therefore WATCH is now optional for `zephyr_check_cache()` and watch for
BOARD variable will be enabled when boilerplate has completed all board
handling.

Several variables must be set by the time boilerplate.cmake is run.
This includes BOARD, SHIELD, CONF_FILE, and DTC_OVERLAY_FILE.
It's not always clear to users that this is the case, and we sometimes
see attempts to modify these variables in app CMakeLists.txt files
after find_package(Zephyr ...) lines, where they will have no effect.
This causes confusion.
Add a new extension function, zephyr_boilerplate_watch(), which traps
attempts to set these variables and prints a noisy warning. Use it
from boilerplate.cmake on the variables mentioned above.
This will hopefully make it clearer at build time why the changes are
