[coreboot] [commit] r5412 - in trunk/src: cpu/intel/model_6ex mainboard/kontron/986lcd-m mainboard/roda/rk886ex

Author: stepan
Date: Tue Apr 13 01:04:29 2010
New Revision: 5412
URL: https://tracker.coreboot.org/trac/coreboot/changeset/5412

Log:
move model_6ex car to a single file. No more .c files that only consist of a
single several pages long asm statement

Could use some renumbering of post codes, but that's good for another time.
