commit 28614bdf1f95f45a48ded0b404373bbe52df8399 Author: Brenton Dong brenton.m.dong@intel.com Date: Tue Oct 18 11:35:15 2016 -0700
drivers/intel/fsp2_0: add FSP TempRamInit & TempRamExit API support
FSP v2.0 Specification adds APIs TempRamInit & TempRamExit for Cache-As-Ram initialization and teardown. Add fsp2_0 driver support for TempRamInit & TempRamExit APIs.
Verified on Intel Leaf Hill CRB and confirmed that Cache-As-Ram is correctly set up and torn down using the FSP v2.0 APIs without coreboot implementation of CAR init/teardown.
