9ca3f61947 cmake: convert WEST_PYTHON path to be correct CMake style
The `WEST_PYTHON` reported by west (python) may use a different path
style (casing and separator) than the path style in CMake
find_package(Python3).

This may result in following additional error text when west version is
not meeting the minimum required version:

    The Python version used by west is:  c:\python37\python.exe
    The Python version used by CMake is: C:/Python37/python.exe
    This might be correct, but please verify your installation.

Using `get_filename_component` will return the path in same style as
CMake find_package(Python3).

25d57ba5af modules: adding support for ROOTs definitions in zephyr/module.yml
Fixes: #25215

This commit introduces the possibility of defining ROOTs in a Zephyr
module and have it automatically appended to list of other ROOTs.
Supported with this commit:
- BOARD_ROOT
- SOC_ROOT
- DTS_ROOT
- ARCH_ROOT

In order to support this in Zephyr module files, the detection of west
has been moved to dedicated west.cmake file and included immediately
after python.cmake.

Also the inclusion of zephyr_modules.cmake has moved before first use
of BOARD_ROOT.

5f7cc8ded9 cmake: kconfig: support for multiple SOC_ROOT
This commit introduces support for multiple SOC_ROOT.

This means that additional SOC_ROOTs specified using -DSOC_ROOT as
argument to CMake will be forming a list together with ${ZEPHYR_BASE}.

This allows for greater flexibility, as developers can now specify
multiple out-of-tree SoCs and not worry about the SoC used for the
board they compile for.

Also it avoid code, such as:
if(BOARD STREQUAL my_board_using_out_of_tree_soc)
  set(SOC_ROOT some/out/of/tree/soc/path)
endif()
in application CMakeLists.txt.

Finally, allowing multiple SOC_ROOTs prepares for specifying SOC_ROOTs
in Zephyr modules.

9c92baa73f devicetree: use edt.pickle more
Consolidate creation of edtlib.EDT objects from a build directory's
devicetree into one place by loading it from build/zephyr/edt.pickle
everywhere. A previous commit creates edt.pickle from gen_defines.py.

In addition to probably speeding things up slightly by not reparsing
the devicetree, the main benefit of this approach is creating a single
point of truth for the bindings directories and warnings
configuration, meaning we don't have to worry about them getting out
of sync while being passed around between devicetree creation and
usage time.

ba5f627815 scripts: size_report: rework to use pyelftools...
...instead of GNU binutils to extract DWARF information.
This is now a bit more portable across OS and toolchain.
One bouns is that this nows with on qemu_x86_64.

A few differences are:
() z_mrsh_* which are aliases to handler_no_syscalls() are now
   dropped as they are mapped to the same address, so that they
   are not counted multiple times.
() Static functions and variables with same names should now be
   attributed to the correct source files instead of being
   accumulated into the same symbol of one file (e.g. multiple
   thread_entry() in kernel tests).
() The totals for ROM and RAM are calculated from the
   corresponding sections. Previous script includes the debug
   sections as total ROM size which is not entirely correct.

b08309e992 cmake: fix kconfig targets
Commit 269f350487 introduced a new
mechanism for loading the edtlib.EDT representation of the devicetree
from kconfigfunctions.py.

While this works for running kconfig.py from kconfig.cmake using
execute_process(), it doesn't work when kconfigfunctions.py is loaded
by the menuconfig target or any other Kconfig targets that use
add_custom_target().

The reason why is that these targets' environments do not have the
location of the EDT pickle file available. This is unlike kconfig.py,
which executes using the same environment as cmake itself, where
edt.pickle's location is already available in the environment.

Fix that by adding EDT_PICKLE to the environment for menuconfig and
friends.

a043d48c54 cmake: fix the build on windows
Commit ef3c5e5516 changed the way
WEST_TOPDIR is initialized from calling 'west topdir' as a subprocess
to using the west API.

However, WEST_TOPDIR is a cmake variable and must be a cmake-style
path, with forward slashes. While 'west topdir' as a command does
output a forward slash separated path (basically in order to make the
zephyr build system work), west_topdir() as an API returns the path in
the host environment path style, which on Windows uses backslashes.

This turns out to be the ultimate cause of the following build error:

CMake Error at C:/.../CheckCCompilerFlag.cmake:41 (set):
  Syntax error in cmake code when parsing string
    -fmacro-prefix-map=C:\Users\Marti\zp=WEST_TOPDIR

Fix it by converting to POSIX style in Python. We could have
potentially also done this using file(TO_CMAKE_PATH "${WEST_TOPDIR}"
...), but I'm intentionally repeating the old way of doing things
since it was known to work.

ef3c5e5516 cmake: west: invoke west using same python as rest of build system
When running CMake, then Python3 will be used.
This is detected through FindPython3, with a preference for using the
python or python3 in path, if any of those matches the required Python
minimal version in Zephyr.

It is also possible for users to specify a different Python, as example
by using:
`cmake -DPYTHON_PREFER=/usr/bin/python3.x`

However, when running `west` as native command, then west will be
invoked on linux based on the python defined in:
`west` launcher, which could be: `#!/usr/bin/python3.y`

Thus there could be mismatch in Pythons used for `west` and the python
used for other scripts.

This is even worse on windows, where a user might experience:
```
>.\opt\bin\Scripts\west.exe --version
Traceback (most recent call last):
  File "C:\Python37\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  ...
  File "C:\Python37\lib\socket.py", line 49, in <module>
    import _socket
ImportError: Module use of python38.dll conflicts with this version of
Python.
```

when testing out a newer Python, but the python in path is still a 3.7.

By importing `west` into zephyr_module.py and by using, as example
`python -c "from west.util import west_topdir; print(topdir())"`
we ensure the same python is used in all python scripts.

Also it allows the user to control the python to use for west.

It also ensures that the west version being tested, is also the version
being used, where old code would test the version imported by python,
but using the west in path (which could be a different version)

If the west version installed in the current Python, and west invocation
is using a different Python interpreter, then an additional help text
is printed, to easier assist users with debugging.

13642fe013 cmake: west: west flash dependencies in sync with CMake flash target
This commit creates a list of a phony targets for each runner, that is:
`west_flash_depends`, `west_debug_depends`, and so on.
Those targets has identical dependencies as CMake runner target.
flash, debug, debugserver, attach targets.

As example `ninja flash` correctly ensures dependencies are taken into
consideration before calling `west flash`.

Unfortunately, calling `west flash` directly would not re-run the flash
dependencies, cause `west flash` would only build the default CMake
target.

Now, `west flash` calls the phony `west_flash_depends` target, ensuring
all deps are up-to-date before flashing (unless --skip-rebuild is given)

The same is true for the other mentioned runners.

The current name `FLASH_DEPS` is misleading in the sense that this

Therefore this is now named `RUNNERS_DEPS` instead.

0b4b3ae4dd cmake, samples, tests: Use semi-accurate project names
When using an IDE (e.g. Eclipse, Qt Creator), the project name gets
displayed. This greatly simplifies the navigation between projects when
having many of them open at the same time. Naming multiple projects
"NONE" defeats this functionality.

This patch tries to use sensible project names while not duplicating
too much of what is already represented in the path. This is done by
using the name of the directory the relevant CMakeLists.txt file is
stored in. To ensure unique project names, small, manual adjustments
have been done.

it so dts.cmake won't do anything with the installed dtc.

0e6ede8929 kconfig: Rename CONFIG_FLOAT to CONFIG_FPU
This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this
symbol only indicates that the hardware Floating Point Unit (FPU) is
used and does not imply and/or indicate the general availability of
toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point
library).

Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of
the symbol that enables the FPU.

c8f7cd5462 kconfig: Make the CPU_HAS_FPU_DOUBLE_PRECISION option global.
This option now applies to the RISC-V architecture and is no longer
a ARM only configuration.
