From 406effd59075cab212c5bf9c1a12759c8fad50a4 Mon Sep 17 00:00:00 2001 From: Dave Frodin Date: Wed, 20 May 2015 10:33:51 -0600 Subject: northbridge/amd/pi: Add support for memory settings This adds support for binarypi based boards that have to make adjustments to the memory configuration settings. A PlatformMemoryConfiguration[] table that describes the memory configuration must be defined in the mainboard folder.
