History
cgd 4c2cff7209 use pci_map_register(). map both mem and I/O spaces, preferring mem space 
by default if it's usable, but falling back to I/O space if mem isn't usable.
If NCR_IOMAPPED is defined (default on the x86), prefer I/O space
then fall back to mem.  Also, clean up the various memory consistency checks
so that they can deal with run-time determination of whether or not the
device is to be memory- or I/O-mapped.

$NetBSD: README,v 1.2 1994/10/27 04:21:29 cgd Exp $

This directory contains files which are used during PCI configuration
and PCI device drivers.  Eventually, most of the device drivers and
some of the configuration support should become machine-independent
and be moved to a more general location.

The configuration support was implemented according to the `PCI Local
Bus Specification, Production Version, Revision 2.0' dated April 30,
1993.  Section numbers referred to in the code may be specific to that
edition of the specification.

Some attempt has been made to insure that the code works on rogue
machines where the BIOS doesn't do its job, but in general I can't
guarantee that.
