This patch contains support for the romImage build target V2. The resulting romImage file should be burned to rom or flash and could be used as small boot loader. Board code should keep their setup code in the file romimage.h located in their mach include directory. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
