From ae738acdc5f02d232e035538c67d63ba19b9ccaa Mon Sep 17 00:00:00 2001 From: Lee Leahy Date: Sun, 24 Jul 2016 08:03:37 -0700 Subject: cpu/x86: Support CPUs without rdmsr/wrmsr instructions Quark does not support the rdmsr and wrmsr instructions. In this case use a SOC specific routine to support the setting of the MTRRs. Migrate the code from FSP 1.1 to be x86 CPU common. Since all rdmsr/wrmsr accesses are being converted, fix the build failure for quark in lib/reg_script.c. Move the soc_msr_x routines and their depencies from romstage/mtrr.c to reg_access.c.
