Author: stepan Date: 2010-01-25 14:15:17 +0100 (Mon, 25 Jan 2010) New Revision: 5053
Removed: trunk/src/northbridge/intel/e7520/raminit_test.c trunk/src/northbridge/intel/e7525/raminit_test.c Modified: trunk/src/northbridge/intel/e7520/Config.lb trunk/src/northbridge/intel/e7525/Config.lb Log: This code was copied from amdk8 and never really made usable. It's supposed to be a userspace regression test for ram init, but in fact, it doesn't even execute ram init. This was suggested by Carl-Daniel on 2009-08-27 Thus, dropping it.
