commit e05d9a97ca0936025e281c81af3657ed8decace2 Author: Subrata Banik subrata.banik@intel.com Date: Wed Jul 27 05:30:50 2016 +0530
intel/fsp1_1: Add C entry support to locate FSP Temp RAM Init
FSP temp ram init was getting called earlier from ROMCC bootblock. Now with C entry boot block, it is needed to locate FSP header and call FspTempRamInit.
Hence add fsp 1_1 driver code to locate FSP Temp ram and execute.
BUG=chrome-os-partner:55357 BRANCH=none TEST=Built kunimitsu and ensure FSP Temp Ram Init return success
