From e7778ec153e279e451bf7c55c05c76e76b095875 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 19 Jan 2015 11:33:47 +0100 Subject: [PATCH] arm: maxbcm: Enable SPL to include DDR training code into U-Boot This patch adds SPL support to the maxbcm MV78460 based board. Including the fixed DDR configuratrion needed for the DDR training code. And the the serdes PHY init code.
