Subject: [PATCH 1/4] microblaze: fix 'FORCE prerequisite is missing' warning
Date: Wed, 15 Jan 2025 03:13:51 +0900 [thread overview]
Message-ID: <20250114181359.4192564-1-masahiroy@kernel.org> (raw)
If you add foo.dtb into the arch/microblaze/boot/dts/ directory and
run 'make simpleImage.foo', you will observe the following warning:
arch/microblaze/boot/dts/Makefile:15: FORCE prerequisite is missing
Without FORCE, if_changed cannot detect the command line changes.
