Torsten Rasmussen 384fb1e478 cmake: introduce EXTRA_DTC_OVERLAY_FILE for devicetree
This commit introduces EXTRA_DTC_OVERLAY_FILE.

This allows users to specify additional devicetree overlays in addition
to a sample / board specific default devicetree overlay files.

It also allows snippets to provide extra devicetree overlays on addition
to sample / board specific overlays.

The name EXTRA_DTC_OVERLAY_FILE clearly indicates the purpose and
follows the naming scheme of EXTRA_ in front of variable name.

Torsten Rasmussen 3a345682ba cmake: introduce EXTRA_CONF_FILE and deprecate OVERLAY_CONFIG
This commit introduces EXTRA_CONF_FILE and deprecates OVERLAY_CONFIG.

It has often caused confusion that OVERLAY_CONFIG adds extra
configuration fragments to the value of CONF_FILE (default: prj.conf),
but the similar named variable DTC_OVERLAY_FILE replaces the default
dtc overlay file used by the build system.

To remove such confusion, this commit introduces the EXTRA_ prefix in
front of CONF_FILE to clearly indicate it's purpose.

Torsten Rasmussen 8460d91e32 cmake: extend zephyr_get() to support fetching of multiple variables
This commit extends zephyr_get() to support multiple variable names to
be fetched into a single variable.

Example:
  zephyr_get(FOO VAR FOO_A FOO_B FOO_C)

will lookup each FOO_A, FOO_B, FOO_C for supported scopes and return
the value in FOO of the first scope encountered having one of the
variables defined.

If MERGE is specified, then all scopes for all vars are looped and the
variable values are merged into FOO and returned.

This functionality will allow to deprecate user-facing settings while
ensuring that both the new and deprecated variables are considered
in zephyr_get() and also taking into consideration the scope with
highest precedence.

This allows Zephyr CMake to do:
  zephyr_get(FOO VAR FOO DEPRECATED_FOO)

  zephyr_get(BAR MERGE VAR BAR DEPRECATED_BAR)

This allows support of old and new setting for a given number of
releases.

Grzegorz Swiderski af23628e43 sysbuild: Add SB_OVERLAY_CONFIG
This fixes a minor issue in sysbuild, where `-DOVERLAY_CONFIG=...` would
be applied not only to the main application, but also sysbuild itself.
This was incorrect, because sysbuild imports a different Kconfig tree
than normal Zephyr builds, so the same Kconfig fragment file would not
necessarily be valid for both.

This adds a new variable SB_OVERLAY_CONFIG to resolve this ambiguity.
It functions along the lines of SB_CONF_FILE, with both being sysbuild-
specific versions of existing variables.

To ensure that OVERLAY_CONFIG is still passed on to the main application
verbatim, its value is now loaded in `configuration_files.cmake`, rather
than `kconfig.cmake`. This is because the former file is not imported by
sysbuild, and it is where the related variables, such as CONF_FILE and
DTC_OVERLAY_FILE, are loaded as well.

Marc Herbert acb7f71ae5 cmake: sparse: fix handling of (deprecated) -DSPARSE=garbage
Due to many layers of indirections (Github Actions, Docker scripts, SOF
build scripts, etc.), thesofproject/sof/pull/7452's first attempt to
turn off VLAs ended up setting `-DSPARSE=gar bage`:

  west build ...  -- '-DSPARSE=y -DCONFIG_LOG_USE_VLA=n'

Quoting issues are typical when trying to pass parameters through too
many layers of indirections. In this case, the mistake set the $SPARSE
variable to the 'y -DCONFIG_LOG_USE_VLA=n' garbage which printed this
confusing and time-consuming error message:

    Setting SPARSE=y -DCONFIG_LOG_USE_VLA=n is deprecated.

Worse: this enabled sparse (!) while silently ignoring the garbage
trailing after "y".

1. Enable sparse only when $SPARSE is equal to "y" and nothing
   else. This stops enabling sparse when `-DSPARSE=gar bage` which draws
   more attention to the warning and gives a little more incentive to
   leave the deprecated option behind. Don't make any difference between
   the "n" and "gar bage" values because $SPARSE is deprecated so not
   worth that much CMake code.

2. Add quotes in the deprecation message to make garbage values more
   obvious, now:

    Setting SPARSE='y -DCONFIG_LOG_USE_VLA=n' is deprecated.

Martí Bolívar 53ab5fcf1c cmake: modules: add generated_file_directories
Due to Hyrum's Law, there are users out in the wild depending on this
directory existing to place their own generated files, so it'd break
things unnecessarily to not do this if we don't have a DTS, as
explained in a source code comment.

However, this doesn't really have anything to do with DTS processing,
so split it into its own module to separate concerns. This isn't
really a CMake module in the usual sense of something that defines
functions you can use, and is therefore a form of technical debt. The
decision was made to accept this because fixing this is a larger task
for the files in cmake/modules/, since there are multiple other
examples of this in here.

This also paves the way for inserting another module in between the
generated_file_directories and dts modules that itself depends on
these directories existing.

Marti Bolivar 06c9bf47b3 snippets: initial snippet.yml support
Add a new script, snippets.py, which is responsible for searching
SNIPPET_ROOT for snippet definitions, validating them, and informing
the build system about what needs doing as a result.

Use this script in snippets.cmake to:

- validate any discovered snippet.yml files
- error out on undefined snippets
- add a 'snippets' build system target that prints all snippet
  names (analogous to 'boards' and 'shields' targets)
- handle any specific build system settings properly,
  by include()-ing a file it generates

With this patch, you can define or extend a snippet in a snippet.yml
file anywhere underneath a directory in SNIPPET_ROOT. The snippet.yml
file format has a schema whose initial definition is in a new file,
snippet-schema.yml.

This initial snippet.yml file format supports adding .overlay and
.conf files, like this:

  name: foo
  append:
    DTC_OVERLAY_FILE: foo.overlay
    OVERLAY_CONFIG: foo.conf
  boards:
    myboard:
      append:
        DTC_OVERLAY_FILE: myboard.overlay
        OVERLAY_CONFIG: myboard.conf
    /my-regular-expression-over-board-names/:
      append:
        DTC_OVERLAY_FILE: myregexp.overlay
        OVERLAY_CONFIG: myregexp.conf

(Note that since the snippet feature is intended to be extensible, the
same snippet name may appear in multiple files throughout any
directory in SNIPPET_ROOT, with each addition augmenting prior ones.)

This initial syntax aligns with the following snippet design goals:

- extensible: you can add board-specific support for an existing
  snippet in another module

- able to combine multiple types of configuration: we can now apply a
  .overlay and .conf at the same time

- specializable: this allows you to define settings that only apply
  to a selectable set of boards (including with regular expression
  support for matching against multiple similar boards that follow
  a naming convention)

- DRY: you can use regular expressions to apply the same snippet
  settings to multiple boards like this: /(board1|board2|...)/

This patch is not trying to design and implement everything up front.
Additional features can and will be added to the snippet.yml format
over time; using YAML as a format allows us to make
backwards-compatible extensions as needed.

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.

  path that much older versions needed.
* newlib isn't supported with oneApi so set TOOLCHAIN_HAS_NEWLIB to

* 2023.0.0 doesn't back llvm-nm, so use binutils version.  This

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.

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.

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

This change was later reverted in CMake >=3.23.2 and >=3.24.0

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.

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 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.

- Zephyr SDK
- Generic (host) C compiler

this causes host tools shipped with Zephyr SDK, such as openocd to not
be discovered unless in path.

Restore the original order so that Zephyr SDK is located first so that
host tools from the SDK can be found without having them in path.

Torsten Rasmussen 980c22c92d cmake: move deprecated code to FindDeprecated.cmake
Move deprecated XCC_USE_CLANG setting to deprecated module.

Deprecated and move the use of CROSS_COMPILE to deprecated module as we
have had ZEPHYR_TOOLCHAIN_VARIANT==cross-compile for a long time.

Deprecated code is now loaded with a single line:
> find_package(Deprecated COMPONENTS XCC_USE_CLANG CROSS_COMPILE)

Torsten Rasmussen 2f1637c4b4 cmake: introduce Deprecated module
The deprecated CMake module allows Zephyr to move deprecated code to a
centralized location from where it's both easy to get an overview of
deprecated code, and remove the code when it has been deprecated long
enough.

It further improve existing code, as the real CMake code now can be
changed from n-lines of deprecated code into a single line of the form:
find_package(Deprecated COMPONENTS <deprecated_name>)

Torsten Rasmussen 7131d02fa4 cmake: rework of target toolchain handling
Follow-up: #41301

This commit is a rework and cleanup of the target toolchain handling in
Zephyr CMake build system.

Instead of directly loading code a CMake modules for target toolchain
lookup, the target toolchain now follows the CMake `find_package()`
pattern for finding the target toolchain.

This makes it more clear which modules are responsible for finding tools
and which modules provides build integration / features.

The following tools can now be found using `find_package()`:
- Target toolchain: find_package(TargetTools)

Torsten Rasmussen 8d2998d4f9 cmake: rework of host tools and generic toolchain handling
Follow-up: #41301

This commit is a rework and cleanup of the tools handling in Zephyr
CMake build system.

Instead of directly loading code a CMake modules for tool lookup, the
host tools now follows the CMake `find_package()` pattern for finding
programs / tools in module mode.

This makes it more clear which modules are responsible for finding tools
and which modules provides build integration / features.

The following tools can now be found using `find_package()`:
- Zephyr-sdk        : find_package(Zephyr-sdk <version>)
- Generic host tools: find_package(HostTools)

This further allows us to decouple the `verify-toolchain` CMake script
part required by `twister` into a tool lookup module and a dedicated
CMake script which utilizes the lookup module.

Torsten Rasmussen 2bace34be3 cmake: remove unreachable Zephyr-SDK lookup code
Removing Zephyr-SDK code for searching and printing messages when Zephyr
SDK is not found in the system.

After Zephyr SDK has been made available on all platforms, including
MacOS and Windows, then `find_package(Zephyr-sdk)` is always invoked
and thus either `find_package(Zephyr-sdk)` will fail or
ZEPHYR_TOOLCHAIN_VARIANT will be defined.

Meaning the removed code block in this commit can no longer be reached.

Torsten Rasmussen 8f8f6cfde3 cmake: cleanup search for devicetree compiler, dtc
Cleanup CMake code by moving devicetree compiler detection to dedicated
FindDtc.cmake module.

This allows us to re-use existing CMake find_package() functionality in
module mode and thus reduce CMake logic.

It further has the benefit of being able to directly specify dtc version
like this:
> find_package(Dtc 1.4.6)

Torsten Rasmussen 9a12f8b68b cmake: move testing of compile flag in environment to top CMakeLists.txt
This moves the test of compile flags set in environment from generic
toolchain to top-level ${ZEPHYR_BASE}/CMakeLists.txt.

In order to cleanup and make Zephyr CMake modules more generic then
the testing of specific compile flags and warn user is not really a
toolchain module responsible but a implementation detail of the project
itself as to how compile flags should be applied in a project.

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.
