Subject: ARM: sa11x0/assabet: ensure CS2 is configured appropriately
X-Git-Tag: v3.2.54~171
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5275be6714bfcc5efe8685ecc3b558e9a0371e06;p=people%2Fms%2Flinux.git

ARM: sa11x0/assabet: ensure CS2 is configured appropriately

commit f3964fe1c9d9a887d65faf594669852e4dec46e0 upstream.

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.
