Subject: [PATCH 14/17] selftests/nolibc: add a "defconfig" target
Date: Tue, 19 Jul 2022 23:44:46 +0200 [thread overview]
Message-ID: <20220719214449.2520-16-w@1wt.eu> (raw)
In-Reply-To: <20220719214449.2520-1-w@1wt.eu>
While most archs will work fine with "make defconfig", not all will
do, and it's not always easy to remember the most suitable choice to
use for a specific architecture.
This adds a "defconfig" target to the Makefile so that one may easily
run "make -C ... defconfig" and make sure to clean and rebuild a fresh
config. This is *not* used by default because we want to preserve the
user's config by default.
