Several years ago we started enabling the -Waddress-of-packed-member
warning in commit cf111962e0 for GCC.
Do the same for Clang, since there is no reason not to and the warning
is very useful, especially in protocol stacks.

PUNCOVER_HOST/PUNCOVER_PORT it is possible now to set the host and port
to something else other than the default.
example:
export PUNCOVER_HOST=10.0.1.1
export PUNCOVER_PORT=8088

Commit be40d854c2ccacf14ca3fcfb01bffdc9b075c6c9 introduced the ability
of building Zephyr with deprecation warnings enabled, by making
COMPILER_WARNINGS_AS_ERRORS depend on the newly added DEPRECATION_TEST
Kconfig option. This has the downside of disabling **all** warnings, not
only the deprecation ones.
This patch instead makes DEPRECATION_TEST disable only the deprecation
warning, but leaves COMPILER_WARNINGS_AS_ERRORS enabled.
This has the advantage of being able to see other unrelated warnings
(and fail if they appear) but has the disadvantage of not printing out
the deprecation warnings themselves (since they are disabled).

The build system currently generates mapfiles by invoking ld with the

The existing logic caused a regeneration when any of the .conf files
changed, but modifying the Kconfig files can also cause the .config file
to become out of date e.g. by adding a new config option or by changing
the default value of a config option (when that default is not
overridden by a .conf).
Without this change, an incremental build wouldn't pick up the new value
and would require the user to notice that and manually do a clean build.

Although xt-clang is based on clang, for some reason, it still
lists xcc system include path as the first search path (e.g.
for stddef.h), and the clang system include path as last. This
creates a big issue when the code starts to use any standards
past C89 (since xcc is based on GCC 4.2). We can use compiler
property nostdin_include to add -isystem to compiler options.
However, some modules (e.g. picolibcs) somehow ignore this.
So we also need to forcibly do add_compile_options() to make
sure the clang system include path is placed before the xcc
system include path.

zephyr_append_cmake_library attempts to warn the user if a user calls it
to create a Zephyr library while the build is in application mode. At
that stage of the build, the list of Zephyr libraries has already been
processed so the function is effectively a no-op.
This heuristic used to determine if the build was in kernel mode or
application mode checked for the presence of the zephyr_prebuilt target.
This check was broken by a previous commit that renamed this target.
This commit fixes the heuristic by checking for the zephyr_pre0 target.
This was tested by calling zephyr_append_cmake_library from some
application build files, building the application, and seeing the
warning only for the call I added. No warnings were printed for any
Zephyr internal libraries.

"-fshort-enums" changes the ABI. It's not enabled for gcc, so it's not
clear why it's enabled for clang (only ARM) and armclang, other than it
looks like some users of these toolchains may be linking against code
that is compiled with "-fshort-enums".
As an example, when compiling with clang, CONFIG_LTO, and a toolchain
built without "-fshort-enums", the linker warns:
ld.lld: error: linking module flags 'min_enum_size': IDs have
conflicting values in

Make the image devicetrees available to sysbuild for advanced use cases.
This is done by calling `zephyr_dt_import` on each image target. The DT
target properties are all expected to be prefixed with `DT_`, so there
should be no conflicts.
Thus, the DT contents of a given `<image>` can be retrieved using e.g.:
dt_nodelabel(<var> NODELABEL <label> TARGET <image>)
as noted in `extensions.cmake`.
Signed-off-by: Grzegorz Swiderski <grzegorz.swiderski@nordicsemi.no>
The CMake dt_* API is backed by target properties. By default, it uses
the target named `devicetree_target` that is initialized in `dts.cmake`.
We should be able to customize this, now that we have a function for
loading those properties into a different target. For example:
zephyr_dt_import(EDT_PICKLE_FILE /path/to/edt.pickle TARGET target)
dt_nodelabel(node NODELABEL label TARGET target)
This would make it possible to reference multiple devicetrees in the
same build system, particularly sysbuild.
