Subject: [PATCH 1/4] Makefile: add buildsystem version variable
Date: Wed, 23 Sep 2020 12:34:15 +0200 [thread overview]
Message-ID: <20200923103418.11186-1-s.trumtrar@pengutronix.de> (raw)
Introduce a new variable to store a buildsystem version information.
The exact information that is stored here (git commit, git tag,...) is
defined by the buildsystem.
It is intended to have the possibility to get information about the
exact barebox binary, environment and configuration.
The variable is utilized the same as KERNELVERSION for linux:
make BUILDSYSTEM_VERSION=$COMMITISH
Via scripts/mkcompile_h this information is injected into the barebox
codebase.
