* Here is the rest of the map, which we're not specifying:

* 1fe.0101.0000 - 1fe.0101.00ff PCI A configuration header
* 1fe.0200.0000 - 1fe.0200.ffff PCI A I/O space
* 1fe.0201.0000 - 1fe.0201.ffff PCI B I/O space
* 1ff.0000.0000 - 1ff.7fff.ffff PCI A memory space
* 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)
* 1ff.0000.0000 - 1ff.ffff.ffff PCI memory space (divided)
