From 7e8702a00fe88590c2ece93061da4a40adf3c242 Mon Sep 17 00:00:00 2001 From: Wenyou Yang Date: Mon, 1 Feb 2016 18:12:15 +0800 Subject: [PATCH] arm: at91/spl: mpddrc: add struct atmel_mpddrc_config MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add struct atmel_mpddrc_config to accommodate the mpddrc register configurations, not using the mpddrc register map structure, struct atmel_mpddrc, in order to increase readability and reduce run-time memory use.
