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. The CBMEM location code implicitly assumes TOM does not change between romstage and ramstage. TOM is set by romstage raminit, and is never changed by romstage or ramstage afterward. As the CBMEM location is positioned at a specific offset from TOM that is known to both romstage and ramstage early CBMEM is safe on Fam10h systems. TEST: Booted ASUS KFSN4-DRE and verified both cbmem timestamp tables from romstage and cbmem log tables from ramstage.
