From 2627c7e2c100c702d540a277aa578176516d3a7c Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 11 Mar 2016 22:07:26 -0700 Subject: x86: broadwell: Add support for SDRAM setup Broadwell uses a binary blob called the memory reference code (MRC) to start up its SDRAM. This is similar to ivybridge so we can mostly use common code for running this blob.
