Subject: [PATCH 11/13] kconfig: do not use allnoconfig_y option
Date: Sun, 14 Mar 2021 04:48:34 +0900 [thread overview]
Message-ID: <20210313194836.372585-11-masahiroy@kernel.org> (raw)
In-Reply-To: <20210313194836.372585-1-masahiroy@kernel.org>
allnoconfig_y is a bad hack that sets a symbol to 'y' by allnoconfig.
allnoconfig does not mean a minimum set of CONFIG options because a
bunch of prompts are hidden by 'if EMBEDDED' or 'if EXPERT', but I do
not like to do a workaround this way.
Use the pre-existing feature, KCONFIG_ALLCONFIG, to provide a one
liner config fragment. CONFIG_EMBEDDED=y is still forced under
allnoconfig.
No change in the .config file produced by 'make tinyconfig'.
The output of 'make allnoconfig' will be changed; we will get
CONFIG_EMBEDDED=n because allnoconfig literally sets all symbols to n.
