73199f2c91 scripts/Kconfig: add dt_node_str_prop_equals Kconfig function
Add function to check if a property of a node
is equal to a passed string.

The motivation is that in current USB device support
the sizes of bulk endpoints are configured in Kconfig.
The information if a USB device controller supports
high-speed comes from devicetree. This information must be
mapped in controller driver Kconfig and corresponding options
in USB device stack configured must be adjusted.

1c911290e9 kconfig: add support for warnings when using experimental features
This adds two new Kconfig settings.

The first setting `EXPERIMENTAL` which is a promptless symbol.
This symbol must be selected by any setting which is used to enable
an experimental feature.

The second setting is `WARN_EXPERIMENTAL` which is a user controlled
setting that configures the build system to print a warning when
experimental features are enabled.

d33fc38e09 scripts: menuconfig: proper handling of NULL character as input
Fixes: #33212

Upstream PR: https://github.com/ulfalizer/Kconfiglib/pull/103

Ignoring when user inputs NULL in a text field.
menuconfig exits with a python stack trace if NULL is provided as input
character, therefore ignore NULL as an input character to prevent this
behaviour.

A NULL character may be given accidentally by the user through the
following ways:
- Pressing `Win` key on keyboard (Windows only)
- Pressing `<CTRL>-@` / `<CTRL>-2`.

5332847644 dts: separate DT libraries from gen_defines.py
We are now in the process of extracting edtlib and dtlib into a
standalone source code library that we intend to share with other
projects.

Links related to the work making this standalone:

    https://pypi.org/project/devicetree/
    https://python-devicetree.readthedocs.io/en/latest/
    https://github.com/zephyrproject-rtos/python-devicetree

This standalone repo includes the same features as what we have in
Zephyr, but in its own 'devicetree' python package with PyPI
integration, etc.

To avoid making this a hard fork, move the code that's being made
standalone around in Zephyr into a new scripts/dts/python-devicetree
subdirectory, and handle the package and sys.path changes in the
various places in the tree that use it.

From now on, it will be possible to update the standalone repository
by just recursively copying scripts/dts/python-devicetree's contents
into it and committing the results.

This is an interim step; do NOT 'pip install devicetree' yet.
The code in the zephyr repository is still the canonical location.

(In the long term, people will get the devicetree package from PyPI
just like they do the 'yaml' package today, but that won't happen for
the foreseeable future.)

This commit is purely intended to avoid a hard fork for the standalone
code, and no functional changes besides the package structure and
location of the code itself are expected.

8165008f44 dts: remove legacy macro support
The legacy macros were first deprecated in Zephyr v2.3. Now that
Zephyr v2.4 has been released, that makes two releases where these
macros have been deprecated, so it's OK to remove them.

This leaves support for legacy binding syntax in place. Removing that
is left to future work.

We need to update various pieces of documentation related to flash
partitions that never got updated when the new API was introduced.
Consolidate this information in the flash_map.h API reference page,
since that's really where users will run into it. This also gives us
the opportunity to improve this documentation.

Adjust a couple of kconfigfunctions.py and sanitycheck bits to use
non-legacy edtlib APIs.

was not used by anything else. The custom trace points unfortunatly were
not accurate and this test was delivering informatin that conflicted
with other tests we have due to placement of such trace points in the

For such measurements we are planning to use the tracing functionality
in a special mode that would be used for metrics without polluting the
architecture and kernel code with additional tracing and timing code.

Furthermore, much of the assembly code used had issues.

d0f082dd3b kconfig/devicetree: Print path to headers when configuring
Change the output during CMake configure from

    Devicetree configuration written to .../devicetree.conf
    Parsing /home/ulf/z/z/Kconfig
    Loaded configuration '.../frdm_kw41z_defconfig'

    Parsing /home/ulf/z/z/Kconfig
    Loaded configuration '.../frdm_kw41z_defconfig'
    Merged configuration '.../prj.conf'
    Configuration saved to '.../.config'
    Kconfig header saved to '.../autoconf.h'

devicetree_unfixed.h is more useful to be aware of than devicetree.conf
(still hoping we can get rid of it at some point), and seeing the
Kconfig header clarifies things to.

"Saved" instead of "written" for consistency. Maybe it could say
"Kconfig configuration" instead of "configuration" too, though it gets a
bit spammy in other contexts where the message shows up.

Updates Kconfiglib (and menuconfig/guiconfig, just to sync) to upstream
revision 061e71f7d7, to get this commit in, which is used to print the
header path:

    Return a message from Kconfig.write_autoconf()

    Like for Kconfig.write_config() and Kconfig.write_min_config(),
    return a string from Kconfig.write_autoconf() with a message saying
    that the header got saved, or that there were no changes to it. Can
    be handy in tools.

    Also make the "no change" message for the various files more
    specific, by mentioning what type of file it is (configuration,
    header, etc.)

    Return True/False from Kconfig._write_if_changed() to indicate if
    the file was updated. This also allows it to be reused in
    Kconfig.write_min_config().

45050dda48 kconfig/cmake: Improve reconfiguration behavior
There are some issues with the behavior when rerunning CMake in an
already initialized build directory:

 1. The check for assignments to promptless symbols in configuration
    fragments isn't run when reconfiguring, because it only runs if
    zephyr/.config doesn't exist

 2. As outlined in
    https://github.com/zephyrproject-rtos/zephyr/issues/9573, you can
    get into situations where zephyr/.config is invalid (e.g. due to
    being outdated), but menuconfig/guiconfig can't be run to fix it

 3. If kconfig.py fails while merging fragments during reconfiguration,
    it will ignore the fragments during the next reconfiguration and use
    the existing zephyr/.config instead, because the fragment checksum
    is calculated and saved before running kconfig.py

(Footnote: The input configuration file(s) to kconfig.py can be either a
list of configuration fragments, when merging fragments, or just
zephyr/.config, if the merged configuration is up-to-date. The output
configuration file is always zephyr/.config.)

To fix the first two issues, explicitly tell kconfig.py when it's
dealing with handwritten configuration input (fragments), via a new
--handwritten-input-configs flag. This is more robust than checking
whether zephyr/.config exists, which was the old logic.

When dealing with handwritten input, there should be no assignments to
promptless symbols. Assignments to promptless symbols is expected in
zephyr/.config however, because it doubles as configuration output.

When running menuconfig/guiconfig, the input configuration is
zephyr/.config rather than configuration fragments, so this change also
makes sure that menuconfig can always be run as long as zephyr/.config
exists and is up-to-date.

To fix the last issue, only write the checksum for the configuration
fragments if kconfig.py succeeds (which means it wrote a
zephyr/.config).

Also improve naming a bit, add help texts for the command-line
parameters to kconfig.py, and simplify write_kconfig_filenames() by
moving logic into it.

Partial fix for
https://github.com/zephyrproject-rtos/zephyr/issues/9573, without the
part in #issuecomment-469701831. Can still run into issues when e.g.
when CMake files can't make sense of settings.

The assert has never hit and probably won't be useful. Shorten the code
a bit.

bb4a4e79dc scripts: kconfig.py: Detect all assignments to promptless symbols
Assigning to promptless symbols has no effect.

Previously, the only check was for whether the value assigned to a
symbol matched its final value. This misses cases where a promptless
symbol is assigned to and just happens to get the assigned-to value as
its final value.

Instead, detect whether configuration files are being merged (by
checking if zephyr/.config already exists), and explicitly check for
assignments to promptless symbols in that case. We can't do it when
zephyr/.config already exists (and is being loaded), because it includes
values for promptless symbols as well.

With the no-prompt check moved out, also use a more specific message for
it, and remove stuff related to prompts elsewhere. Shorten messages a
bit at the same time, and add two warn() and err() helpers.
