2354f055ec toolchain: arcmwdt: add compile options: -Wno-typedef-redefinition
Without the -Wno-typedef-redefinition option, arcmwdt (clang based)
complains if a typedef gets redefined in gnu99  mode (since this is
officially a C11 feature). While new versions of GCC do not seem to
issue this warning in gnu99 mode anymore. So some existing code
with typedef redefined which works well with GCC will issue this
warning. As this warning is not fatal, so simply shut it off for good.

1368295183 cmake: fix DTS handling of multiple overlay files
This commit fixes an issue where providing a list of overlay files for
dts was not handled correctly.
The means that using `-DDTC_OVERLAY_FILE="file1.overlay;file2.overlay"`
would fail as those two file names would be concatenated into a single
file name.

This is fixed by properly quote the `DTC_OVERLAY_FILE` variable.

8165008f44 dts: remove legacy macro support
The legacy macros were first deprecated in Zephyr v2.3. Now that
Zephyr v2.4 has been released, that makes two releases where these
macros have been deprecated, so it's OK to remove them.

This leaves support for legacy binding syntax in place. Removing that
is left to future work.

We need to update various pieces of documentation related to flash
partitions that never got updated when the new API was introduced.
Consolidate this information in the flash_map.h API reference page,
since that's really where users will run into it. This also gives us
the opportunity to improve this documentation.

Adjust a couple of kconfigfunctions.py and sanitycheck bits to use
non-legacy edtlib APIs.

2d2fea8732 cmake: create zephyr_get_targets() functions

zephyr_get_targets() provides a mechanism for retrieving all CMake

build time significantly.

eb2a705497 cmake: support absolute path in zephyr_code_relocate() function
Fixes: #27288

The Zephyr CMake function `zephyr_code_relocate()` would treat any file
argument as relative to `CMAKE_CURRENT_SOURCE_DIR` even if an absolute
path is provided.

A file with absolute path would thus become
`${CMAKE_CURRENT_SOURCE_DIR}/<absolute-path>/<file>` which leads to a
non existing file.

This is fixed by checking if path argument is a relative path, and only
use `CMAKE_CURRENT_SOURCE_DIR` in such case.

fb16a3deb0 cmake: ensure consistent behavior between x_ROOT settings
Fixes: #23825

Today, BOARD, SOC, ARCH, DTS, KCONFIG, and TOOLCHAIN_ROOT can be
specified by users or through other CMake files.

It is not clear if relative paths are permitted and/or from where a
relative path is constructed.

Inside CMake, it is very easy to specify `${ZEPHYR_BASE}`,
`${CMAKE_CURRENT_SOURCE_DIR}`, or similar, thus there is no reason to
use relative path inside CMake, as it easy can lead to discussion on
relative to what.

For users manually invoking CMake using, `cmake ... <app-dir>` it is
nice to have to possibility to specify a relative path.
For this purpose, relative path are considered relative to the
`APPLICATION_SOURCE_DIR`.

This commit updates:
- BOARD_ROOT
- SOC_ROOT
- ARCH_ROOT
- DTS_ROOT
- KCONFIG_ROOT
- TOOLCHAIN_ROOT

to allow paths relative to `APPLICATION_SOURCE_DIR` when specified with
`-D<type>_ROOT=<relative-path>`

a5917f0af4 cmake: export build flags to external build systems excluding SHELL tag
Fixes: #28230

The introduction of CMake SHELL prefix in compile options to avoid
symbol de-duplication caused the build flag export feature to fail.

The export itself works, but unfortunately CMake only strips `SHELL`
prefix for its own compiler invocation, and not when exporting the build
flags.

This causes `SHELL` to be present in the Makefile.exports.<language>
files, leading to problems in external build systems.

This is fixed by using `zephyr_get_compile_options_for_lang()` that
strips `SHELL` and use the returned value for the export handling.

To ensure all compile options has been defined, then the inclusion of
`cmake/makefile_exports` has been moved to the end of
`zephyr/CMakeLists.txt` file.

5c10eafb2b cmake: improved handling of CONF_FILE cached variable
Fixes: #28134

Minor fix for correctly testing if CONF_FILE variable is defined, and
if it is defined, then a current scope variable will be set with same
name. For a variable that is already present in current scope this has
no effect, but a cached variable (such as one provided with -DCONF_FILE)
will now have both a current scope and cached definition.
This ensures that current scope CONF_FILE will continue to be defined
even when the cached variable is cleared later.

Clearing of the cached variable ensures correct detection if user later
re-invokes CMake with a new -DCONF_FILE value.

The cached version is cleared later in favor of the CACHED_CONF_FILE
that is used between multiple CMake invocations.

b94ce67899 cmake: get Zephyr settings for language extension
This commit updates the get Zephyr settings functions to be able to
handle settings if those settings are expressed using a generator
expression.

As example, zephyr_get_include_directories_for_lang(...) would prefix
each include property of zephyr_interface with `-I`, like this:
Property: include;include/generated;lib/libc/minimal/include
becomes: `-Iinclude -Iinclude/generated -Ilib/libc/minimal/include`

But if the property contains a generator expression:
Property: include;$<TARGET_PROPERTY:compiler,some_include>
becomes: -Iinclude -I$<TARGET_PROPERTY:compiler,some_include>
and in case that property is a list, this results in:
`-Iinclude -Iinclude/list_item1;include/list_item2;include/list_itemN`
and thus breaking the build.

This is fixed by using `$<JOIN:<list>>` expression instead, which
ensures all list item, regardless of provided as simple list or through
the usage another generator expression, will always expand correctly.

Functions updated in the commit:
- zephyr_get_include_directories_for_lang
- zephyr_get_system_include_directories_for_lang
- zephyr_get_compile_definitions_for_lang
- zephyr_get_compile_options_for_lang

The sample `application_development/external_lib` has been updated
according to those changes.

This commit fixes an issue in the process_flags function.
The function check a list of flags for generator expression for provided
language, for example:

In case the flag contains multiple generator expression, then the
current substitution fails.

This commit keep existing behaviour for simple cases, but extends the
more complex cases into a always enabled generator expression, that is
$<$<COMPILE_LANGUAGE:C>:$<ADDITIONAL_EXPRESSION>> into
$<1:$<ADDITIONAL_EXPRESSION>>
and
$<$<FIRST_EXPRESSION>$<COMPILE_LANGUAGE:C>:--flag> into
$<$<FIRST_EXPRESSION>$<1:--flag>

3124c02987 cmake: flash/debug: refactor runner configuration
This commit message is a bit of a novel mostly:

- because the issues involved are longstanding
- as evidence this is not a capricious refactoring

The runners.core.RunnerConfig Python class holds common configuration
values used by multiple runners, such as the location of the build
outputs and board directory.

The runners code, first written in 2017-ish, replaced various shell
scripts that got this information from the environment. Avoiding
environment variables was a requirement, however. It's ghastly to set
environment variables for a single command invocation on Windows, and
the whole thing was part of a larger push to make Zephyr development
on Windows better.

I had a hammer (the argparse module). Finding a replacement naturally
looked like a nail, so the information that ends up in RunnerConfig
got shunted from the build system to Python in the form of 'west
flash' / 'west debug' command line options like '--board-dir',
'--elf-file', etc.

I initially stored the options and their values in the CMake cache.
This was chosen in hopes the build system maintainer would like
the strategy (which worked).

I knew the command line arguments approach was a bit hacky (this
wasn't a nail), but I also honestly didn't have a better idea at the
time.

It did indeed cause issues:

- users don't know that just because they specify --bin-file on the
  command line doesn't mean that their runner respects the option, and
  have gotten confused trying to flash alternate files, usually for
  chain-loading by MCUboot (for example, see #15961)

- common options weren't possible to pass via board.cmake files
  (#22563, fixed partly via introduction of runners.yaml and the west
  flash/debug commands no longer relying on the cache)

- it is confusing that "west flash --help" prints information about
  openocd related options even when the user's board has no openocd
  support. The same could be said about gdb in potential future use
  cases where debugging occurs via some other tool.

Over time, they've caused enough users enough problems that
improvements are a priority.

To work towards this, put these values into runners.yaml using a new
'config: ...' key/value instead of command line options.

For example, instead of this in the generated runners.yaml file:

args:
  common:
  - --hex-file=.../zephyr.hex

we now have:

config:
  hex_file: zephyr.hex

and similarly for other values.

In Python, we still support the command line options, but they are not
generated by the build system for any in-tree boards. Further work is
needed to deprecate the confusing ones (like --hex-file) and move the
runner-specific host tool related options (like --openocd) to the
runners that need them.

Individual board.cmake files should now influence these values by
overriding the relevant target properties of the
runners_yaml_props_target.

For example, instead of:

  board_runner_args(foo "--hex-file=bar.hex")

Do this:

  set_target_properties(runners_yaml_props_target PROPERTIES
                        hex_file bar.hex)

This change additionally allows us to stitch cmake/mcuboot.cmake and
the runners together easily by having mcuboot.cmake override the
properties that set the hex or bin file to flash. (The command line
arguments are still supported as-is.)

Combined with 98e0c95d91ae16f14e4997fb64ccdf0956595712 ("build:
auto-generate signed mcuboot binaries"), this will allow users to
build and flash images to be chain loaded by mcuboot in a way that
avoids calling 'west sign' and passing 'west flash' its output files
entirely.

While we are here, rename runner_yml_write to runners_yaml_append().
This function doesn't actually write anything, and we're here
refactoring this file anyway, so we might as well improve the
situation while we're at it.

0950b2549e dts: support specifying preprocessor flags for devicetree
In some cases it is useful to use the C preprocessor to control the
content of a devicetree file.  A specific use case is in testing,
where different combinations of node properties must be checked.
Provide a mechanism to allow arbitrary preprocessor flags to be passed
through CMake to affect the devicetree content.

f66a0c3772 build: auto-generate signed mcuboot binaries
Add new Kconfig options which depend on CONFIG_BOOTLOADER_MCUBOOT:

- CONFIG_MCUBOOT_SIGNATURE_KEY_FILE: the path to the key pair which
  should be used to sign the image, in PEM format. This is sent to
  imgtool via 'west sign' when set to produce zephyr.signed.bin and
  zephyr.signed.hex files as needed.

- CONFIG_MCUBOOT_EXTRA_IMGTOOL_ARGS: additional arguments to pass to
  imgtool.

- CONFIG_MCUBOOT_GENERATE_CONFIRMED_IMAGE: also generate
  zephyr.signed.confirmed.{bin,hex}

Add build system support for these options.

This makes a separate 'west sign' step unnecessary when using MCUboot,
if the application image is properly configured with the location of
the key file.

79b1f89f7d cmake: west detection fixes and improvements
Starting with west 0.8, we will have a stable way to run west as a
python module. In west 0.7, we have an undocumented way.

Handle these two cases to override the WEST variable used by the build
system to run west inside the same python interpreter as the rest of
the build system. This makes it intuitive to shell out to west from
elsewhere in the build, without making people reimplement existing
commands in the west API when it is not necessary.

Do so for the 'west topdir' invocation in west.cmake as an example.

The check that looks for whether PYTHON_EXECUTABLE and WEST_PYTHON
match is also not working properly when symbolic links are in use.
Fix it by using REALPATH instead of ABSOLUTE in the
get_filename_component() calls.

Finally, print the error on a failed import that we expect to work.

2fa48f79d1 cmake: warn user if CPPFLAGS is set as environment setting
Zephyr doesn't use CFLAGS, CXXFLAGS, and CPPFLAGS if they are defined
in environment.

In case user defines CFLAGS or CXXFLAGS in environment, then a warning
message is printed, however CPPFLAGS does not raise a warning.

CPPFLAGS is updated to follow the principle of CFLAGS and CXXFLAGS.

4e8a991590 cmake: Zephyr module error on module name current
In CMake, ZEPHYR_CURRENT_MODULE_DIR is used during processing of module
CMakeLists.txt files.
If a module is named `current` then it's corresponding
`ZEPHYR_<module_name>_MODULE_DIR` would become ZEPHYR_CURRENT_MODULE_DIR
and thus colliding with internal Zephyr CMake variable.

Using module name `current` is therefore forbidden.
Print an error to users when a module named `current` is used in
Zephyr.

a861fc96b2 cmake: export Zephyr modules as Kconfig variables.
In CMake it is possible to reference each Zephyr module as a CMake
variable. This commit introduces the same feature to Kconfig, so that
it is possible to reference a module in consistent way in both CMake
and Kconfig.

To include a file from module FOO in CMake, use:
include(${ZEPHYR_FOO_MODULE_DIR}/somefile.cmake

To source a file from module FOO in Kconfig, use:
source "$(ZEPHYR_FOO_MODULE_DIR)/Kconfig.somefile"

ab7ec17b86 cmake: zephyr module processing improvements.
This commit improves Zephyr modules support in CMake.
All Zephyr modules will now have a corresponding
`ZEPHYR_${module_name}_MODULE_DIR` set, regardless of whether they
define a cmake folder in module.yml.

This results in:
`ZEPHYR_${module_name}_MODULE_DIR` defined for all modules and refers to
the root of the modle.
`ZEPHYR_${module_name}_CMAKE_DIR` defined for modules that specifies
cmake in module.yml, or is having both a CMakeLists.txt and Kconfig file
in the zephyr folder.
