	 * 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
	 * Ultra5 and Ultra10 machines uses slightly differrent addresses
	 * 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)

/*
 * For the physical addresses split into 3 32 bit values, we deocde
 * them like the following (IEEE1275 PCI Bus binding 2.0, 2.2.1.1
 * Numerical Representation):
 *
 * 	phys.hi cell:	npt000ss bbbbbbbb dddddfff rrrrrrrr
 * 	phys.mid cell:	hhhhhhhh hhhhhhhh hhhhhhhh hhhhhhhh
 * 	phys.lo cell:	llllllll llllllll llllllll llllllll
 *
 * where these bits affect the address' properties:
 *	n	not-relocatable
 *	p	prefetchable
 *	t	aliased (non-relocatable IO), below 1MB (memory) or
 *		below 64KB (reloc. IO)
 *	ss	address space code:
 *		00 - configuration space
 *		01 - I/O space
 *		10 - 32 bit memory space
 *		11 - 64 bit memory space
 *	bb..bb	8 bit bus number
 *	ddddd	5 bit device number
 *	fff	3 bit function number
 *	rr..rr	8 bit register number
 *	hh..hh	32 bit unsigned value
 *	ll..ll	32 bit unsigned value
 * the values of hh..hh and ll..ll are combined to form a larger number.
 *
 * For config space, we don't have to do much special.  For I/O space,
 * hh..hh must be zero, and if n == 0 ll..ll is the offset from the
 * start of I/O space, otherwise ll..ll is the I/O space.  For memory
 * space, hh..hh must be zero for the 32 bit space, and is the high 32
 * bits in 64 bit space, with ll..ll being the low 32 bits in both cases,
 * with offset handling being driver via `n == 0' as for I/O space.
