[PATCH 3.12 003/212] ARM: sa11x0/assabet: ensure CS2 is configured appropriately

[Greg Kroah-Hartman]

3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Russell King <rmk+kernel@xxxxxxxxxxxxxxxx>

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.
