	 * 1ff.8000.0000 - 1ff.ffff.ffff	PCI B memory space
	 *
	 * NB: config and I/O space can use 1-4 byte accesses, not 8 byte
	 * accesses.  Memory space can use any sized accesses.
	 *
	 * Note that the SUNW,sabre/SUNW,simba combinations found on the

	 * than the above.  This is mostly due to the fact that the APB is
	 * a multi-function PCI device with two PCI bridges, and the U2P is
	 * two separate PCI bridges.  It uses the same PCI configuration
	 * space, though the configuration header for each PCI bus is
	 * located differently due to the SUNW,simba PCI busses being
	 * function 0 and function 1 of the APB, whereas the psycho's are
	 * each their own PCI device.  The I/O and memory spaces are each
	 * split into 8 equally sized areas (8x2MB blocks for I/O space,
	 * and 8x512MB blocks for memory space).  These are allocated in to
	 * either PCI A or PCI B, or neither in the APB's `I/O Address Map
	 * Register A/B' (0xde) and `Memory Address Map Register A/B' (0xdf)
	 * registers of each simba.  We must ensure that both of the
	 * following are correct (the prom should do this for us):
	 *
	 *    (PCI A Memory Address Map) & (PCI B Memory Address Map) == 0
	 *
	 *    (PCI A I/O Address Map) & (PCI B I/O Address Map) == 0
	 *
	 * 1fe.0100.0000 - 1fe.01ff.ffff	PCI configuration space
	 * 1fe.0100.0800 - 1fe.0100.08ff	PCI B configuration header
	 * 1fe.0100.0900 - 1fe.0100.09ff	PCI A configuration header
	 * 1fe.0200.0000 - 1fe.02ff.ffff	PCI I/O space (divided)
