From dfcb76089ada89a5520ad8544440799e75f01227 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>

Subject: [PATCH] sh: se7206: Make the I/O port routines less stupid.

The port routines were logically inverted, and the MRSHPC range had
no upper bound, causing 8 and 16-bit port I/O to get mangled.
