* kconfig: update to Linux 5.2-rc4Masahiro Yamada2019-06-191-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous sync was Linux 4.20. This updates Kconfig to Linux 5.2-rc4. I adjusted the top Makefile as well because Linux commit 058507195b53 ("kbuild: move ".config not found!" message from Kconfig to Makefile") moved the .config check from Kconfig to Makefile. I also made auto.conf a mandatory include file, and remove it from the prerequisites of other targets. We are safe because Make is immediately terminated when syncconfig fails to generate auto.conf. Highlights: - The parser has no more shift/reduce conflicts - The lexer was rewritten more simply - The token lookup table was deleted - Replace license boilerplates with SPDX - Compile C files as separate units - Do not overwrite .config when the content was not changed - Lots of bug-fixes and cleanups Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* kconfig: sync to Linux 4.20Masahiro Yamada2019-01-031-0/+47
The previous sync was commit 18895514dc5e ("kconfig: update to v3.18-rc6"). Some commits were applied on top of that since then, but equivalent fixups were done in Linux. So, this commit overwrites everything scripts/kconfig/ with the one from Linux 4.20 Highlights: - 'silentoldconfig' has been renamed to 'syncconfig' (the top Makefile needs to be adjusted) - 'testconfig' target has been added for unit-tests (the top Makefile needs to export PYTHON3 because the test frame relies on Python3 and pytest) - The perfect hash table generated by gperf has been removed - The localization support has been removed - The 'option env=VAR' has been replaced with more generic variable reference syntax $(VAR) (./Kconfig and common/Kconfig need to be adjusted) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
