Subject: [PATCH] kconfig: add KCONFIG_ALLCONFIG support for tinyconfig
Date: Thu, 03 Mar 2022 17:51:02 +0100	[thread overview]
Message-ID: <87k0dbosis.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.
