From f3964fe1c9d9a887d65faf594669852e4dec46e0 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 16 Oct 2013 00:09:02 +0100 Subject: [PATCH] ARM: sa11x0/assabet: ensure CS2 is configured appropriately The CS2 region contains the Assabet board configuration and status registers, which are 32-bit. Unfortunately, some boot loaders do not configure this region correctly, leaving it setup as a 16-bit region. Fix this.
