Makefile: Strip leading spaces when preprocessing generated_defconfig

2025-05-05T20:17:23+00:00

Clang's preprocessor may emit extra spaces for lines starting with '#'.
Lines with these extra characters cannot be handled by Kconfig and will
be ignored with warnings like,

        unexpected data:  # CONFIG_OF_BOARD_FIXUP is not set

Those options that is expected to be assigned explicitly with N will be
set to the default value, messing up board configurations.

Let's sed these spaces away to ensure board configurations could be
correctly generated with Clang.

Makefile: Improve generated_defconfig file handling

2024-03-13T22:47:11+00:00

Commit 2027e99e61aa ("Makefile: Run defconfig files through the C
preprocessor") adds `generated_defconfig' file, but fails to clean that
up. It might be useful to have that file around after `make' is done,
but it's better to clean that up on `make clean'. Also we probably want
to hide it in `git status' list. This patch makes the described changes,
and also adds `-P' parameter to the CPP command that produces the
`generated_defconfig' to avoid generating linemarkers.

Makefile: Run defconfig files through the C preprocessor

2024-01-12T13:34:19+00:00

This allows us to use some of the normal preprocessor directives inside
defconfig files. Such as #define and #include.

scripts: kconfig: Add config fragment support in board/../

2023-08-09T13:21:42+00:00

Add support to config fragments (.config) located in the /board
directory. This will allow only base defconfigs to live in /configs and
all fragments to live in their respective device directory in /board/..

kconfig / kbuild: Re-sync with Linux 4.20

2021-07-14T20:57:35+00:00

Align Kconfig and Kbuild logic to Linux 4.20 release with minimal impact
on files outside of this scope.

Our previous Kconfig sync was done by commit 587e4a429698 ("kconfig /
kbuild: Re-sync with Linux 4.19").

As part of this re-sync, a few related changes from previous Linux
releases were found to have been missed and merged in, and are not in
the following list.

The imported Linux commits are:

[From prior to v4.19]

There are a number of changes related to additional warnings as well as
being able to drop cc-name entirely that have been omitted for now as
additional work is required first.
