From 052b317b866076458c3a1e17f0f20ee9c7411f0b Mon Sep 17 00:00:00 2001
From: Brad Smith <brad@cvs.openbsd.org>
Date: Mon, 20 Oct 2008 19:43:40 +0000
Subject: - Remove sys/cdefs.h header. - Make use of pci_matchbyid(). - Replace
 magic number with PCI_MAPREG_START for the PCI BAR. - Remove redundant code
 to enable PCI bus mastering which is already   dealt with by
 pci_mapreg_map().
