Projects such as Zephyr OS have a module system, where Kconfig files can
exist in multiple directories that are effectively merged together by the
build system. In other words, one project directory can refer to
subdir/Kconfig where subdir/ is actually in another project directory.
As an example:
zephyr/ - main source directory
Kconfig - main Kconfig file
module/ec - module directory
motion/ - motion subsystem
Kconfig - Kconfig file for motion subsystem
Wtih the above, we might have, in zephyr/Kconfig:
source "motion/Kconfig"
and it automatically locates the file in the module/ec directory.
Add support for this, by allowing a list of search paths to be supplied to
Kconfiglib.

When parsing Kconfig which include macros it is currently necessary to provide a value for all macros in advance. This may not be possible in some cases, e.g. when the caller is performing checks on the Kconfig options but is not running a full build of the project. Add an option to support this. This allows parsing of Zephyr Kconfig files without specifying a particular board, etc. Signed-off-by: Simon Glass <sjg@chromium.org>

Add some changes to allow this library to work with Zephyr: - Ability to have Kconfig files in multiple projects directories - Ability to ignore variable expansion failures, since there are so many Kconfig variables in Zephyr These changes have been sent upstream here: ulfalizer/Kconfiglib#112 and to Zephyr here: zephyrproject-rtos/zephyr#42233 so this also includes the one Zephyr-local commit: 66d1b3ce106 kconfig: kconfiglib.py: Backup files only All three commits are based on Kconfiglib 14.1.0 BUG=b:181323955 BRANCH=none TEST=python3 util/test_kconfig_check.py Signed-off-by: Simon Glass <sjg@chromium.org> Change-Id: Iac24a90fe3707cacab40d45210addc663bb17f60 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/3390708 Reviewed-by: Jack Rosenthal <jrosenth@chromium.org>

Rather unfortunately, it appears the original author of Kconfiglib disappeared. The Zephyr project has been granted ownership of the PyPI package via PEP-541 request, and I'm going to do a release based on a new repository in the ➡️ Action required: @sjg20 Are you able to re-open your pull request on the new repository? |

Here are a few useful features I needed with working with Zephyr OS.
