From 47d19da4d3f9ac4787abe9dee32406478424be52 Mon Sep 17 00:00:00 2001
From: Ilya Yanok <yanok@emcraft.com>
Date: Mon, 8 Jun 2009 04:12:46 +0400
Subject: [PATCH] serial_mx31: allow it to work with mx27 too and rename to
 serial_mxc

UART hardware on i.MX27 is the same as on the i.MX31 so we just
need to provide the driver with correct address of the registers.
