From f4b20af9d716ff57d78d5d576e2990903bd70842 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Mon, 20 Feb 2017 13:33:32 -0800 Subject: drivers/intel/{fsp1_1,fsp2_0}: Provide separate function for fsp load Add a function to allow FSP component loading separately from silicon initialization. This enables SoCs that might not have stage cache available during silicon initialization to load/save components from/to stage cache before it is relocated or destroyed. BUG=chrome-os-partner:63114 BRANCH=None TEST=Compiles successfully.
