X-Git-Url: http://git.dujemihanovic.xyz/%22/img/sics.gif/%22/static/git-favicon.png?a=commitdiff_plain;h=c8630bb09674e2b8496753929ac4d0a610583f1e;p=u-boot.git

ARM: rmobile: rcar-common: Zap arch_preboot_os()

v2018.01 commit e23eb942ad103f ("ARM: rmobile: Stop using
rcar-common/common.c on Gen3") removed
board/renesas/rcar-common/common.c from the build chain with the
reasoning that calling arch_preboot_os() is no longer needed.

However, it left the arch_preboot_os() in place. Get rid of it.
This is done in preparation of resurrecting rcar-common/common.c.

NOTE: The three removed header includes (io.h, sys_proto.h, rcar-mstp.h)
are in direct relationship with the dropped arch_preboot_os() hook. The
other headers (common.h, rmobile.h) are going to be needed by pretty
much anything that is going to appear in the rcar common code. So, keep
the two in place.
