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. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Bin Meng <bmeng.cn@gmail.com>
