This patch changes C7 CAR code to be a single assembler file instead
of the ugly mixture it was before. It also enables CAR for all C7 boards Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Patrick Georgi <patrick.georgi@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5399 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
