Torsten Rasmussen 48321ef252 shield: cmake: adjust if(EXISTS <shield>.conf) to check for right file
Fixes: #32269

This commit is a followup to #31877 where the `${shield_dir}/${s_dir}`
was adjusted to `${SHIELD_DIR_${s}}` to ensure only including shields
and not boards in list of known shields.

An `if(EXISTS ${shield_dir}/${s_dir}...)` was missed in this process
which causes #32269. This is corrected in this commit.

Martí Bolívar 0629e698af cmake: warn if it's too late to set a boilerplate variable
Several variables must be set by the time boilerplate.cmake is run.
This includes BOARD, SHIELD, CONF_FILE, and DTC_OVERLAY_FILE.

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
after find_package(Zephyr ...) lines, where they will have no effect.
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
from boilerplate.cmake on the variables mentioned above.

This will hopefully make it clearer at build time why the changes are
being ignored.

Torsten Rasmussen 2bf26ecf4d cmake: modules: remove Zephyr module duplicates from ZEPHYR_MODULE_NAMES
This allows users to overrule a module from command line.
As example, the Zephyr build system loads the module FOO from
`modules/FOO`, but user has a custom FOO locally at `custom/FOO` and
would like to use this module instead of manifest specified.

If user does `-DZEPHYR_EXTRA_MODULES=custom/FOO` the following error
will be seen:
```
The binary directory

  build/modules/FOO

is already used to build a source directory.  It cannot be used to build
source directory

  custom/FOO

Specify a unique binary directory name.
```

Removing duplicates from the list allows a user to use
`-DZEPHYR_EXTRA_MODULES=custom/FOO` and thus replace `modules/FOO` for
the current build.

Globbing recursively for overlay files also picks up board overlays,
which leads to errors in the shield handling, as user could wrongly
specify certain boards as shields.
Also it led to wrongly list some board as shields, as reported

Daniel Leung ff720cd9b3 x86: enable soft float support for Zephyr SDK
This adds the correct compiler and linker flags to
support software floating point operations. The flags
need to be added to TOOLCHAIN_*_FLAGS for GCC to find
the correct library (when calling GCC with
--print-libgcc-file-name).

Note that software floating point needs to be turned
on for Newlib. This is due to Newlib having floating
point numbers in its various printf() functions which
results in floating point instructions being emitted
from toolchain. These instructions are placed very
early in the functions which results in them being
executed even though the format string contains
no floating point conversions. Without using CONFIG_FPU
to enable hardware floating point support, any calls to
printf() like functions will result in exceptions
complaining FPU is not available. Although forcing
CONFIG_FPU=y with newlib is an option, and because
the OS doesn't know which threads would call these
printf() functions, Zephyr has to assume all threads
are using FPU and thus incurring performance penalty as
every context switching now needs to save FPU registers.
A compromise here is to use soft float instead. Newlib
with soft float enabled does not have floating point
instructions and yet can still support its printf()
like functions.

The introduction of Zephyr module glue code in the Zephyr repository
introduces a Kconfig variable in the form of:
`config ZEPHYR_<MODULE_NAME>_MODULE`.

All Kconfig variables go into `autoconf.h`, therefore it is necessary
to sanitize the Kconfig variable, so that it does not contain special
characters. To ensure consistent variable name, then the module name
will be sanitized in all variable use in both Kconfig and CMake.
The sanitization is done be replacing all special characters with an
underscore, `_`.

Torsten Rasmussen 1bd0b29918 cmake: scripts: supporting gen_relocate_app feature in windows
Fixes: #28847

This commit fixes two places that was causing gen_relocate_app to fail
in windows.

gen_relocate_app.py now splits only on first `:` in
`<MEM_REGION>:<file>`.

Windows contains `:` in path, thus only first `:` is valid for splitting
mem region and file path.

Second part of the issue is fixed in CMake where `'` was used for
quoting of command arguments.
This causes a file not found on Windows because the final `'` would be
treated as part of the filename. Similar the first `'` would be treated
as path of the mem region name.

This is fixed by using `"` for quoting, which works correctly on all
platforms.

gen_relocate_app.py:403: UserWarning: File: .../kernel/sem.c' Not found

Torsten Rasmussen 3673e288bd modules: introducing MODULE_EXT_ROOT to allow glue code in Zephyr repo
This commit introduces MODULE_EXT_ROOT which allows CMake and Kconfig
glue code to be placed outside of the Zephyr module repository.

This allows for placing glue code in Zephyr, but also allows users to
specify custom MODULE_EXT_ROOTs for glue code using either
`-DMODULE_EXT_ROOT` or `zephyr/module.yml` with
`build:settings:module_ext_root` settings.

MODULE_EXT_ROOT' is a list of directories, similar to other roots such
as BOARD_ROOT, DTS_ROOT, etc.
The Zephyr repo folder ${ZEPHYR_BASE} is always to the MODULE_EXT_ROOT
list as lowest priority.
For each MODULE_EXT_ROOT, the file
`<module_ext_root>/modules/modules.cmake` will be processed.

In Zephyr repo, the folder `modules/<module>/` contains CMakeLists.txt
and Kconfig glue code for the Zephyr module.

A Zephyr module can specify that CMakeLists.txt and Kconfig glue code is
placed in an external module root by specifying:
```
build:
  cmake-ext: True
  kconfig-ext: True
```

It is still possible to place the CMakeLists.txt and Kconfig files
directly in the Zephyr module using the existing:
```
build:
  cmake: <path>
  kconfig: <file>
```.

Martí Bolívar 0d5e6c13e9 boards/shields: re-work handling in cmake and west
Remove the boards and shields lists from the 'usage' target output.
That might have been readable at some point long ago in Zephyr's
history, when only a few boards were available, but right now it's
obscuring the high level targets we really want 'usage' to print.

Instead, add 'boards' and 'shields' targets which the user can run to
get those lists, and reference them from the 'usage' output. This
makes 'usage' squintable again. We use the new list_boards.py script
from the 'boards' target.

Reference the 'help' target from 'usage' as well, and drop the
recommendation that people run '--target help' from the 'west build
--help' output for the 'west build --target' option. The canonical
place to look is 'usage' now.

Use the new list_boards.py code from 'west boards' as well, which
allows us to add the board's directory as a format string key, in
addition to its name and architecture.

Keep west-completion.bash up to date. While doing that, I noticed that
a bunch of references to this file refer to a stale location, so fix
those too.

Finally, the 'usage' output is what we print for a failed board or
shield lookup, so that needs to be updated also. Handle that by
invoking boards.cmake and a new shields.cmake in CMake script mode to
print the relevant output.

Torsten Rasmussen 77ecd6837d cmake: support versioning of board
This commit introduces support for versioning of boards.
The existing board handling is limited in such a way that it is not
possible to support a specific board in multiple variants.

This commit introduces versioning of board revisions so that it is
possible to support minor variations to a board without having to
defining a completely new board.

This can be done by adding a revision.cmake file in the board folder:
boards/<arch>/<board-dir>/revision.cmake

Depending on the revision format chosen, additional configuration files
for each revision available must also be added, those have the form:
boards/<arch>/<board-dir>/<board>_<revision>.conf

Examples:
boards/<arch>/<board-dir>/<board>_defconfig:  Common board settings

Revision format: MAJOR.MINOR.PATCH
boards/<arch>/<board-dir>/<board>_0_5_0.conf: Revision 0.5.0
boards/<arch>/<board-dir>/<board>_1_0_0.conf: Revision 1.0.0
boards/<arch>/<board-dir>/<board>_1_5_0.conf: Revision 1.5.0

Revision format: LETTER
boards/<arch>/<board-dir>/<board>_A.conf:     Revision A
boards/<arch>/<board-dir>/<board>_B.conf:     Revision B

The `board_check_revision` function is available in `extensions.cmake`
to facilitate board revision handling in `revision.cmake`.

User select the board revision using: `-DBOARD=<board>@<revision>`, as
example `-DBOARD=plank@0.5.0`.

If a shield, test, sample, or application needs to specify DTS overlay
or Kconfig fragments, this can be done by adding revision specific
configuration files in the sample/test/shield folder, like this:
<shield/sample-path>/boards/<board>.conf
<shield/sample-path>/boards/<board>_<revision>.conf

or if there is there is only a need for adjusting on a given board
revision:
<shield/sample-path>/boards/<board>_<revision>.conf

Similar for DTS overlay files:
<shield-path>/boards/<board>.overlay
<shield-path>/boards/<board>_<revision>.overlay

or:
<shield-path>/boards/<board>_<revision>.conf

For test/samples/apps:
<sample-path>/<board>.overlay
<sample-path>/<board>_<revision>.overlay

or:
<sample-path>/<board>_<revision>.overlay

Torsten Rasmussen 7247412a9e cmake: cleanup board and shield cmake code
Cleanup board and shield cmake code so that code duplication is reduced.

Before this commit, the code for verifying if BOARD or SHIELD user input

The common code has been made into a Zephyr extension function so that
all part of Zephyr build system can have a uniform way of checking if
sticky arguments has changed, and print user warning in a uniform way.

This also fixes an undiscovered flaw, where changing a shield is not
possible if a shield was defined at first CMake invocation, but in case
no shield had been specified at all, then build system would wrongly
allow specifying and changing shields, for example doing:
cmake -DBOARD=nrf52840dk_nrf52840 -DSHIELD=sparkfun_sara_r4 <sample>
cmake -DSHIELD=wnc_m14a2a

results correctly in:
> CMake Warning at zephyr/cmake/app/boilerplate.cmake:287 (message):
>   The build directory must be cleaned pristinely when changing shields

and correctly keep existing SHIELD settings.

but doing:
cmake -DBOARD=nrf52840dk_nrf52840 <sample>
cmake -DSHIELD=sparkfun_sara_r4
cmake -DSHIELD=wnc_m14a2a

would not result in any warning, because `CACHED_SHIELD` was not
correctly checked in this case.

Torsten Rasmussen f73da678a4 cmake: use the toolchain path, id and version as extended signature.
Fixes: #30531

Now using MD5 sum of CMAKE_C_COMPILER (path), CMAKE_C_COMPILER_ID and
CMAKE_C_COMPILER_VERSION variables as part of the TOOLCHAIN_SIGNATURE.

Moved MD5 calculation of executable into
cmake/target_toolchain_flags.cmake to have common location, as
CMAKE_C_COMPILER_ID and CMAKE_C_COMPILER_VERSION are not available until
project() has executed.

Christopher Friedt bf304ffed9 cmake: zephyr_module.cmake ZEPHYR_EXTRA_MODULES evaluated too late
Previously, `cmake/app/boilerplate.cmake` evaluated
ZEPHYR_EXTRA_MODULES on line ~548 *after* `zephyr_module.cmake`
was included on line ~168.

This change ensures that modules defined in `ENV{ZEPHYR_EXTRA_MODULES}`
are processed properly through `zephyr_module.cmake`.

Fixes #30673

Martin Åberg 53a4acb2dc SPARC: add FPU support
This change adds full shared floating point support for the SPARC
architecture.

All SPARC floating point registers are scratch registers with respect
to function call boundaries. That means we only have to save floating
point registers when switching threads in ISR. The registers are
stored to the corresponding thread stack.

FPU is disabled when calling ISR. Any attempt to use FPU in ISR
will generate the fp_disabled trap which causes Zephyr fatal error.

- This commit adds no new thread state.
- All FPU contest save/restore is synchronous and lazy FPU context
  switch is not implemented.

Torsten Rasmussen 94288bdcc5 cmake: zephyr_get_<flags>_for_lang_as_string() uses space as delimiter
The use of zephyr_get_<flags>_for_lang_as_string will now use space as
delimiter, this will allow for existing used of the
zephyr_get_<flags>_for_lang_as_string() to return a string with spaces
instead of semicolons as a quoted list.

Note, in most situations it is prefered to have a proper CMake list
returned, in which case zephyr_get_<flags>_for_lang() is probably the
correct function to use.

Torsten Rasmussen 8275d39d4d cmake: adding $<SEMICOLON> instead of space on zephyr_get_compile_<type>
The current zephyr_get_compile_<type> flags returns compile / include
flags based on generator expressions.

But they also included a space.

This have the unintended side-effect that when the properties are
fetched into another variable and later appended to lists in order to
finally be used in a CMake target function / custom command, then CMake
in some cases will quote the string, creating a quoted argument like:
"arg0 arg1 arg2: instead of individual arguments like: "arg0" "arg1"
"arg2".

By using $<SEMICOLON>, then arguments are seperated correctly.

Torsten Rasmussen 6ca2bf25cb cmake: manual handling of CMakeCheckCompilerFlag.cmake inclusion
Fixes: #30232

This is a workaround for #30232.

During Zephyr CMake invocation a plain C compiler is used for DTS.
This results in the internal `CheckCompilerFlag.cmake` being included
by CMake

Later, when the full toolchain is configured, then
`CMakeCheckCompilerFlag.cmake` is included.
This overloads the `cmake_check_compiler_flag()` function, thus
causing #30232.

By manualy loading `CMakeCheckCompilerFlag.cmake` then
`CheckCompilerFlag.cmake` will overload the functions (and thus win the
battle), and because `include_guard(GLOBAL)` is used in
`CMakeCheckCompilerFlag.cmake` this file will not be re-included later.

It also prints a warning informing the user of the issue.

The ; will ensure that the `>` and `outfile` are given as two arguments
and thus ensure correct behavior in all cases.
