19 * Address regions in the PCI address space are not mapped into the
20 * normal memory space of the ColdFire. They must be accessed via
21 * handler routines. This is easy for I/O space (inb/outb/etc) but
22 * needs some code changes to support ordinary memory. Interrupts
23 * also need to be vectored through the PCI handler first, then it
24 * will call the actual driver sub-handlers.
28 * Un-define all the standard I/O access routines.
