From 304b2c684e42af5b72d643322f783d88538dc817 Mon Sep 17 00:00:00 2001 From: Alexander Shiyan Date: Sun, 6 May 2012 09:21:57 +0400 Subject: ARM: clps711x: Using a single definition for the PHYS and VIRT registers offset Using a single definition for the physical and virtual address register for all variants boards clps711x. This patch also includes the use of a single function clps_read/write in some units.
