Modification history
--------------------
01c,08mar00,rcb  Correct prototype for usbPciMemioOffset()...
		 was incorrectly called usbPciMemOffset().
01b,10dec99,rcb  Add definition for usbPciMemioOffset().
01a,31may99,rcb  First.

DESCRIPTION

This file defines platform-independent functions accessing PCI bus 
capabilities.  These functions allow PCI device drivers to be written 
independent of the underlying O/S's PCI access mechanisms.
