Daniel Leung d475f9865b scripts: size_report: add tree node for WORKSPACE
Add a tree node to group files under WORKSPACE so that
they won't be shown with full path. The WORKSPACE is
usually the same as WEST_TOPDIR unless ZEPHYR_WORKSPACE
is defined during build.

Fixes part of: #32448

This commit updates the CMake CMAKE_CXX_LINK_EXECUTABLE to include
crtbegin.o and crtend.o at the right locations when linking with gcc.

It also updates linker scripts to ensure proper location of the
exception header frame sections.

This ensure proper handling of exceptions for those architectures

Carlo Caione 835ff89c40 cmake: arm64: Bail out if the old SDK is used
After the ARM/ARM64 split the SDK 0.12.4 is needed to be able to compile
the ARM64 arch code. Bail out if an old SDK is detected at compile time.

Also change the minimal supported Zephyr SDK to v0.12, as agreed in
Toolchain WG.  Main reason is added compiler architectures and important
inclusion of fixes, for example qemu and arm fixes for veneers (TFM)

Due to the fact that we use -mcpu=hs as a default for ARCv2 HS

Torsten Rasmussen 39f06e0195 ld.bfd: ensure that ld.bfd is preferred over ld.
Fixes: #32237

When building for native_posix, then host tools are used.
This means that gcc will link using `/usr/bin/ld` per default.

If ld points to lld, then linking will fail.

This commit will first look for ld.bfd, and if found then use
-fuse-ld=bfd for linking. If ld.bfd is not found, then ld is used as
fallback as that will be assumed to be the best working candidate.

Torsten Rasmussen 8ff65f4087 cmake: get: using NOT DEFINE BUILD_VERSION instead of NOT BUILD_VERSION
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.

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.

Fixes: Issue reported on slack.

Torsten Rasmussen 6360593f99 cmake: west: do not print error if west topdir fails
`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.
```

found but Zephyr is not in a west workspace (`west topdir` fails)

Torsten Rasmussen ffff2124d3 cmake: zephyr_file() now accepts BOARD and BOARD_REVISION as argument
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.

Torsten Rasmussen b3bb1d6ad2 cmake: make WATCH an optional argument to zephyr_check_cache()
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.

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

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
