From e18cd3d7963dd513b750b35bafe6bfe5b0b038a5 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Fri, 29 Dec 2017 11:47:47 +0530 Subject: [PATCH] arm: emif-common: Add ecc specific emif registers This is a slight difference in emif_ddr_phy_status register offsets for DRA7xx EMIF and older versions. And ecc registers are available only in DRA7xx EMIC. Add support for this difference and ecc registers.
