From 953ab736afa0fca087b9e7626daa28ca7adc9fa8 Mon Sep 17 00:00:00 2001 From: Giuseppe Pagano Date: Fri, 15 Nov 2013 17:42:50 +0100 Subject: [PATCH] udoo: Move and optimize platform register setting. Previous uDoo configuration adopts register settings for DDR3, clock, muxing, etc. taken from Nitrogen6x. uDoo schematics is rather different from that board, and it needs customized setting for most of the registers. All this changes can be considered atomical since it is part of initial support of the board. Patch changes uDoo configuration files path to a specific one, and adopt optimized value for every configured register.
