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.
