From 959f85f8a3223c116bbe95dd8a9b207790b5d4d3 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 27 Sep 2006 16:43:28 +0900 Subject: sh: Consolidated SH7751/SH7780 PCI support. This cleans up quite a lot of the PCI mess that we currently have, and attempts to consolidate the duplication in the SH7780 and SH7751 PCI controllers.
