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

173  * 1fe.0100.0000 - 1fe.01ff.ffff	PCI configuration space
174  * 1fe.0100.0000 - 1fe.0100.00ff	PCI B configuration header
175  * 1fe.0101.0000 - 1fe.0101.00ff	PCI A configuration header
176  * 1fe.0200.0000 - 1fe.0200.ffff	PCI A I/O space
177  * 1fe.0201.0000 - 1fe.0201.ffff	PCI B I/O space
178  * 1ff.0000.0000 - 1ff.7fff.ffff	PCI A memory space
179  * 1ff.8000.0000 - 1ff.ffff.ffff	PCI B memory space
180  *
181  * NB: Config and I/O space can use 1-4 byte accesses, not 8 byte
182  * accesses.  Memory space can use any sized accesses.
183  *
184  * Note that the SUNW,sabre/SUNW,simba combinations found on the
185  * Ultra5 and Ultra10 machines uses slightly differrent addresses
186  * than the above.  This is mostly due to the fact that the APB is
187  * a multi-function PCI device with two PCI bridges, and the U2P is
188  * two separate PCI bridges.  It uses the same PCI configuration
189  * space, though the configuration header for each PCI bus is
190  * located differently due to the SUNW,simba PCI busses being
191  * function 0 and function 1 of the APB, whereas the Psycho's are
192  * each their own PCI device.  The I/O and memory spaces are each
193  * split into 8 equally sized areas (8x2MB blocks for I/O space,
194  * and 8x512MB blocks for memory space).  These are allocated in to
195  * either PCI A or PCI B, or neither in the APB's `I/O Address Map
196  * Register A/B' (0xde) and `Memory Address Map Register A/B' (0xdf)
197  * registers of each Simba.  We must ensure that both of the
198  * following are correct (the prom should do this for us):
199  *
200  *    (PCI A Memory Address Map) & (PCI B Memory Address Map) == 0
201  *
202  *    (PCI A I/O Address Map) & (PCI B I/O Address Map) == 0
203  *
204  * 1fe.0100.0000 - 1fe.01ff.ffff	PCI configuration space
205  * 1fe.0100.0800 - 1fe.0100.08ff	PCI B configuration header
206  * 1fe.0100.0900 - 1fe.0100.09ff	PCI A configuration header
207  * 1fe.0200.0000 - 1fe.02ff.ffff	PCI I/O space (divided)
208  * 1ff.0000.0000 - 1ff.ffff.ffff	PCI memory space (divided)
