Subject: [PATCH 3/9] kconfig: preset config during all*config
Date: Thu, 3 Nov 2005 16:07:20 +0100 (CET) [thread overview]
Message-ID: <Pine.LNX.4.61.0511031606530.2501@scrub.home> (raw)
Allow to force setting of config variables during
all{no,mod,yes,random}config to a specific value. For that conf first
checks the KCONFIG_ALLCONFIG environment variable for a file name,
otherwise it checks for all{no,mod,yes,random}.config and all.config. The
file is a normal config file, which presets the config variables, but they
are still subject to normal dependency checks.
