Subject: [PATCH v2] kconfig: add KCONFIG_ALLCONFIG support for tinyconfig
Date: Tue, 08 Mar 2022 09:34:16 +0100	[thread overview]
Message-ID: <87v8wo25we.fsf@irisa.fr> (raw)

Since f8f0d06438e5, tinyconfig overrides KCONFIG_ALLCONFIG to include
kernel/configs/tiny-base.config. However, this ignores user's preset if
defined.

This modification checks if the user has set KCONFIG_ALLCONFIG and if so,
concatenates it with kernel/configs/tiny-base.config to be used as preset
config symbols.

Changes in v2:
- Remove `<(echo)` in the cat command as it is not portable
- Add $(srctree) in presets' path to make it compatible with O=<dir>
