downloadcoreboot-967952a102f13825085fdab6e37738d437eca655.tar.xz
Add image updating support. When selecting it, it
expects a coreboot.rom to be available, and adds the files to it. It has no idea how to replace files, it merely adds them. It only works with Tinybootblock and the bootblock is immutable. The "clean" rules allow "make clean-for-update", which removes everything but coreboot.rom Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5103 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
