commit 7067b2a98361dbae5d7c7e86891bba290eb0a08c
Author: Timothy Pearson <tpearson at raptorengineeringinc.com>
Date: Fri Mar 13 13:27:58 2015 -0500
cpu/amd/model_10xxx: Add support for early cbmem
mainboards/amd/fam10: Initialize cbmem area after raminit
When GFXUMA is enabled, CBMEM is placed at TOM - UMASIZE
When GFXUMA is disabled, CBMEM is placed at TOM
This matches the behaviour present before conversion to early
CBMEM.
TEST: Booted ASUS KFSN4-DRE and verified both cbmem timestamp
tables from romstage and cbmem log tables from ramstage.
