Author: mjones Date: 2008-04-23 01:32:56 +0200 (Wed, 23 Apr 2008) New Revision: 3252
Removed: trunk/coreboot-v2/src/cpu/amd/model_10xxx/fidvid_common.c trunk/coreboot-v2/src/cpu/amd/model_10xxx/pstate.c Modified: trunk/coreboot-v2/src/cpu/amd/model_10xxx/Config.lb trunk/coreboot-v2/src/cpu/amd/model_10xxx/model_10xxx_init.c Log: Clean up and remove late initialization code that is no longer needed.
Pstate intialization has moved to early init because it requires a warm reset. Add CPUID setup and disable SMM access to late initialization. Much of this code is leftover from porting from K8.
