a0ba67df63 cmake: remove base_name for dep file
With CMake 3.20 relative path inside DEPFILEs are treated relative to
CMAKE_CURRENT_BINARY_DIR and are transformed by CMake in its internal
dep file.

Therefore Zephyr build system must no longer add `base_name` to the
`-MT` argument for the preprocessor.

3181331586 cmake: bintools: gnu: Suppress GDB check console outputs
The GDB check routine added in the PR #38749 does not suppress the
console outputs (stdout and stderr) and may print out a misleading
error message during a CMake configuration when the required version
of Python is not available on the system:

  arm-zephyr-eabi-gdb: error while loading shared libraries:
  libpython3.8.so.1.0: cannot open shared object file: No such file or
  directory

This commit adds the `OUTPUT_QUIET` and `ERROR_QUIET` options when
executing the GDB process so that the console outputs during the GDB
executable validation are not displayed to the user.

In addition, this commit removes the unused `GDB_PY_NO_PY` standard
output redirection variable since it is unnecessary.

6d72d915f9 cmake: remove platform / build file specific escaping
Fixes: #41435

Remove build host specific escaping of start symbol command argument.
The start symbol for armlink is: Image$$device$$Base
and were escaped as: Image\\$$\\$$device\\$$\\$$Base

However, the $ must only be escaped in Linux and MacOS, not on windows
hosts.

Instead of escaping the start symbol in the CMake code then it is better
to use the VERBATIM flag on `add_custom_command()` which ensures correct
escaping for the build host.

a03e7df9f5 cmake: linker generator replace % with @ for symbol referencing
Fixes: #41435

The use of %<symbol>% works well in Linux and MacOS but when passed
to the linker script generator in Windows the %<symbol>% is processed
by the windows shell causing the value to disappear and thus an empty
value inside the generated ld linker script or scatter file.

This is fixed by using the @ character instead of the % character.

84fe8f8121 cmake: armlink: fix handling of argument in configure_linker_script
The PR #40174 changed `configure_linker_script()` macro from handling a
single string to handle a list of strings for the
linker_pass_define argument.

This changed the armlink/target.cmake from STREQUAL to IN_LIST, however
as `configure_linker_script()` is a macro, then arguments are not
variables in the CMake sense but string replacements, and therefore
IN_LIST doesn't work directly on the argument.

Fix this by creating a true CMake list from the content of the argument
and use this list for IN_LIST checking.

ca0702283f cmake: remove CMake policy CMP0002 and CMP0116
The CMake policies CMP0002 and CMP0116 can now safely be removed.

Setting CMake minimum version to 3.20 ensures that policies are set to
NEW per default for those two policies:
> The cmake_minimum_required() command does more than report an error
> if a too-old version of CMake is used to build a project. It also sets
> all policies introduced in that CMake version or earlier to NEW
> behavior.

CMP0002 was introduced in CMake 2.6 and was set to NEW.

CMP0116 was introduced in CMake 3.20 and set to OLD because of:
> Use the old CMake behaviour until we are updating the CMake 3.20 as
> minimum required. This ensure that CMake >=3.20 will be consistent
> with older CMakes.
and can thus be removed as we are now having 3.20 as minimum required.

2b7c61e306 cmake: re-work devicetree preprocessing steps
This causes any devicetree error messages to refer to the source files
which contain the errors instead of intermediate <BOARD>.dts.pre.tmp
files in the build directory.

Do this using a new python-devicetree feature which can correctly
handle cpp's generated line marker directives.

To use this feature, rework the way that the C preprocessor is run on
devicetree inputs so that line marker directives are preserved by
removing the -P option.

This is a backwards incompatible change to the way the generated files
in the build directory used to work, as not all tools can consume line
markers. In particular, dtc can't handle these lines. We therefore
pass dtc zephyr.dts instead (the final parsed devicetree output from
python-devicetree).

Since <BOARD>.dts.pre.tmp is a publicly documented file, this is
changing existing behavior, so use a new file name for the
intermediate files to make it more obvious that something changed. In
particular, use zephyr.dts.pre instead of <BOARD>.dts.pre.tmp.
(The $BOARD.dts.pre.tmp name is a little cumbersome anyway.)

fc416ca52f cmake: run dtc after gen_defines.py and friends
Curently, any and all devicetree syntax errors are being handled by
dtc, because it runs before gen_defines.py. This means that any
improvements we make to devicetree error handling and reporting in
dtlib or edtlib will never be noticed by users that have dtc
installed.

(This also has the unfortunate effect of hiding dtlib error reporting
from me, since my systems all have dtc installed.)

Move dtc to after gen_defines.py, so that initial error handling and
warnings all come from python. If DTC has some additional warnings or
errors to report, let them come last. They will still halt the build
if anything is wrong.

8346032d19 cmake: extensions: improve DT consistency with python APIs
In the python APIs we use for devicetree, you can generally use an
alias interchangeably with the full path to a node.

For example, dtlib.py says:

    [...] both dt.get_node("/foo/bar") and dt.get_node("bar-alias")
    will return the 'bar' node below:

      /dts-v1/;

      / {
              foo {
                      bar_label: bar {
                              baz {
                              };
                      };
              };

              aliases {
                      bar-alias = &bar-label;
              };
      };

    Fetching subnodes via aliases is supported:
    dt.get_node("bar-alias/baz") returns the 'baz' node.

Now that we have the necessary helper functions for resolving alias
names, make the CMake APIs to devicetree behave the same way. This
improves consistency between the two sets of devicetree helpers used
by the build system, making them both match the general devicetree
practice that an alias is as good as a path. This is good for
consistency.

28b2e55321 cmake: rework linker script generation and linker prebuilt stages
This commit reworks the linker script generation and linking stages in
order to better support fixed section location as required by #38836.

Today we have the following generated linker scripts and the elf output
depending on the system configuration:
- linker_app_smem_unaligned.cmd --> app_smem_unaligned_prebuilt.elf
- linker_zephyr_prebuilt.cmd    --> zephyr_prebuilt.elf
- linker.cmd                    --> zephyr.elf

as not all linker scripts may be created and as there is a need for the
possibility to move gen handles earlier then those stages has been
renamed into more generic names so that with this commit we have:
- linker_zephyr_pre0.cmd --> zephyr_pre0.elf
- linker_zephyr_pre1.cmd --> zephyr_pre1.elf
- linker.cmd             --> zephyr.elf

This also means that is the stage zephyr_pre1 is not needed, then build
can go from `zephyr_pre0.elf` to `zephyr.elf`.

The gen_handles.py has been changed so it now uses `zephyr_pre0.elf` as
input. This ensures that the handles array are final when invoking the
next build and linking stages.

To keep the current behavior of generating the isr table and kobj hash
of what was `zephyr_prebuilt` stage the code blocks contolling isr
generation and kobj hash has been relocated to be located after
app_smem and device handle generation.

fffaf05e5d scripts: support for build meta file creation
This commit is motivated by the west discussion in:
https://github.com/zephyrproject-rtos/west/issues/548

The commit provides the ability to generate a build meta info file
containing lists of:
- Zephyr:         path and revision
- Zephyr modules: name, path, and revision
- West:           manifest path
                  path and revision for each project

For Zephyr or Zephyr modules the revision will be `null` if it is not
under git version control.

If Zephyr, a modules, or a project has uncommitted changes, the revision
will be marked dirty.

If west is not installed or used for the build process, the
west-projects list will be empty.

If a project is both a Zephyr module and a west project it will show up
in both lists.

Similar to Zephyr, which is independently referred as the Zephyr in use
but also listed as west project when west is used.
This is important in case ZEPHYR_BASE was manually set and pointing to
a different Zephyr repository.

The build meta file is not created per default but can be enabled with
the BUILD_OUTPUT_META Kconfig setting.

A project using west and having an extra Zephyr module loaded not
controlled using git can look like:
zephyr:

1198087440 cmake: APPLICATION_CONFIG_DIR support implemented
With this commit a dedicated APPLICATION_CONFIG_DIR is added to the
Zephyr build system.

Currently, the APPLICATION_SOURCE_DIR is identical also the base
location of configuration files.

This is very practical for simple samples, but also has it limitations
for more complex setups.

Introducing a dedicated APPLICATION_CONFIG_DIR allows users more
customization options in Zephyr build system.
Especially in terms of custom build configuration files unknown to
Zephyr itself.

For example, instead of all configuration files being located directly
in the application source folder, a project might prefer to organize
their configuration files on a per board basis, for example:
<app>/boards/custom_board_A/prj.conf
<app>/boards/custom_board_A/app.overlay
<app>/boards/custom_board_A/custom_file.mine
<app>/boards/custom_board_B/prj.conf
<app>/boards/custom_board_B/app.overlay
<app>/boards/custom_board_B/custom_file.mine
...

instead of n-files located in the root of the sample.

If the user / sample specifies APPLICATION_CONFIG_DIR, then this folder
will always be used instead of the default configuration folder.

As part of this extension the behaviour of
`-DCONF_FILE=<relative-path>/prj_<build>.conf` and additional Kconfig
fragments automatic sourcing has been aligned with the default behavior
of `prj.conf`.

2eb13159ec cmake: kconfig: use absolute files for merge_config_files
The `merge_config_files` list contains files with both relative and
absolute paths.
Each entry is checked and files with a relative path are converted to
absolute path. This creates a `merge_config_files_with_absolute_paths`
identical to the `merge_config_files` but with absolute path on each
entry.

Afterwards it is mixed whether `merge_config_files` or
`merge_config_files_with_absolute_paths` are used creating unnecessary
risk when the list with relative path files are used.

This commit sets the content of `merge_config_files` with updated
absolute paths files, and also updates all places to use this list.

This ensures that after path conversion then only the list with absolute
paths is used.

9c74027a7b cmake: CMake linker script generator pass handling
To prepare for linker script creation with flexible number of linker
passes depending on system configuration then the Zephyr CMake linker
script generator has been updated to use pass names instead of pass
numbers.

This allows greater flexibility as a section can now be active based on
the settings on the pass and not the linking pass index number.

As part of this, the `PASS` processing in `linker_script_common.cmake`
has been adjusted so that it properly handles when a linking pass is
handling multiple settings, such as both `LINKER_APP_SMEM_UNALIGNED`
and `DEVICE_HANDLES_PASS1` in same linking pass.

As the number of linking passes are more flexible, then the PASS
argument in `zephyr_linker_section()` and
`zephyr_linker_section_configure()` has been updated to also support
a `NOT <name>` argument, for example: `PASS NOT LINKER_ZEPHYR_FINAL`.

1fa3f15137 cmake: update configure_linker_script() to prepend -D on defines
Currently all calls to `configure_linker_script()` specifies `-D<name>`
when calling `configure_linker_script()`.

This works well for the gcc pre-processed ld linker script templates,
but Zephyr also supports a CMake linker script generator which can be
used for ld scripts and armlink scatter files.

In this case, a `-D` must be stripped.

This commit changes this so that Zephyr CMake build system calls
`configure_linker_script()` without `-D`.
Thus the `LINKER_SCRIPT` choice can decide how this information should
be passed to underlying linker script functionality, that is `-D` for
linker script template and CMake variable for the CMake linker script
generator.

f4d41b1a6c cmake: boards: make QEMU icount sleep parameter configurable
When QEMU is running in icount mode, the behaviour regarding
the CPU being in sleep mode is configurable, with the default
value being set to 'off'. In this case, instruction counting
continues even when the CPU is sleeping or no target time is
set in the system timer. If the sleep parameter is set to
'on', instruction counting stops if the CPU is sleeping, and
the instruction count will fast-forward directly to the next
target time once it is being set.

In the Xilinx derivative of QEMU (which simulates ZynqMP and
Zynq-7000 SoCs), the default configuration causes QEMU to no
longer accept control commands via the console or remotely
whenever Zephyr enters and remains in idle mode.

Therefore, this commit makes the value of the sleep para-
meter of the icount functionality configurable, with the
default value remaining 'off'. The value can be changed at
board level alongside with the specification of the icount
shift value.

429d6cf055 cmake: create zephyr_build_string
This commit creates a new `zephyr_build_string()` function.

`zephyr_build_string()` provides a common way of constructing a build
string based on board name, board revision, and build type.

Having this as a function facilitate creation of names in a common way
and thus helps to ensure naming consistency, especially if newer info
is later embedded into the build string.

Initially the build string will be used to lookup configuration
fragments and devicetree overlay files.

This function is used by `zephyr_file(CONF_FILES ...)`.

a81f8af701 build: Fix native_posix build on GNU GCC
Update -fno-pie to only be added when relevant. This fixes native_posix
builds on Debian hosts.

* Debian and other Linux distributions have ld with --warn-textrel as
default.
* The option generates a warning when linking on x86.
* The warning make scripts/twister fail because we treat all warnings
as error.
* The warning is issued when no PIE objects are linked against PIE
library.
* PIE (Position Independent Executable) or not can be seen with the
following command.
* When you want to generate non PIE, link with `-no-pie.`

Non PIE

  $ readelf -l build/zephyr/zephyr.elf | grep 'Elf file type is'
  Elf file type is EXEC (Executable file)

PIE

  $ readelf -l /lib/x86_64-linux-gnu/libc.so.6 | \
  grep 'Elf file type is'
  Elf file type is DYN (Shared object file)

917d5021d7 cmake: CMake compile features support
Fixes: #36558 #32577

This commit introduces CMAKE_C_COMPILE_FEATURES and
CMAKE_CXX_COMPILE_FEATURES.

This allows users to use the `target_compile_features()` in their own
code.

In Zephyr, the CMAKE_C/CXX_COMPILE_FEATURES are defined based on the
compiler and the Kconfig / CSTD setting.
Doing so ensures that a user compiling Zephyr with c99 and specifies
`target_compile_features(<target> ... c_std_11)` will get an error.
And similar if building Zephyr with C++ support and c++11, but testing
for `target_compile_features(<target> ... cxx_std_17)`.

For example in the C++ case, the user must ensure that Zephyr is
compiled with C++17, that is: CPLUSPLUS=y and STD_CPP17=y, in which case
the CMAKE_CXX_COMPILE_FEATURES will contain support for C++17 and thus
the `target_compile_features(<target> ... cxx_std_17)` will succeed.
