From 91135fef22262b1789abeb1a23efc43460cffa3d Mon Sep 17 00:00:00 2001 From: Marc Jones Date: Tue, 20 Sep 2016 20:36:08 -0600 Subject: mainboard/amd: Copy bettong to gardenia and update for build Use bettong as the reference for the gardenia mainboard. Update makefiles etc so it builds. This patch intentionlly keeps the carrizo_fch.asl file to remain synchronized with the AMD PI package. Remove items that do not apply to the Stoney APU, rewrite the comments associated with the PCIe devices, and fix up the SPD register association to match the 00670F00 chip.h.
