avoid merge commits in coreboot
Merge commits are append-only and exactly preserve development
history. Alert readers noticed that a rebase means that commits
must change. This is frowned upon if someone has already seen the
commits as they were before the rebase, but it is perfectly fine if
they only exist locally.
Using Gerrit allows us to comfortably rework commits until we are
happy with them, without needing to rewrite any branch in
coreboot.git. Gerrit acts as a buffer, where anything goes, until
the commits are "submitted" into coreboot.git.
