From 04ebf598de6d8b8152c99ebe181de084e0b5b242 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Wed, 30 Sep 2015 17:49:04 -0500 Subject: fsp1_1: move relocation algorithm to commonlib In order to support FSP 1.1 relocation within cbfstool the relocation code needs to be moved into commonlib. To that end, move it. The FSP 1.1 relocation code binds to edk2 UEFI 2.4 types unconditionally which is separate from the FSP's version binding. BUG=chrome-os-partner:44827 BRANCH=None TEST=Built and booted glados.
