From 909db6af61bee69faa1bf964ad229c0d93aa4444 Mon Sep 17 00:00:00 2001
From: nyan <nyan@FreeBSD.org>
Date: Sun, 7 Sep 2008 04:44:24 +0000
Subject: - Add the i386_memio_map_load() function to load I/O address table. -
 Add the bus_space_compare macro for bus_space consistency. - Switch using the
 bus_space_map_load() in isa_load_resourcev().
