janitor task: unify and cleanup naming.
cache_as_ram_auto.c and auto.c are both called "romstage.c" now. 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@5092 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
