From 9ade1217c9ba39ad2f004a898ddfbb815fd5fe74 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>
Date: Mon, 20 Apr 2009 15:38:25 +0900
Subject: [PATCH] sh: pci: Drop asm-generic/pci.h, so we can use our own
 fixups.

The new PCI code wants its own bus<->resource mappings instead of the
generic equivalents, so drop the asm-generic include in preparation.
