142 * Here is the rest of the map, which we're not specifying:
143 *
144 * 1fe.0100.0000 - 1fe.01ff.ffff PCI configuration space
145 * 1fe.0100.0000 - 1fe.0100.00ff PCI B configuration header
146 * 1fe.0101.0000 - 1fe.0101.00ff PCI A configuration header
147 * 1fe.0200.0000 - 1fe.0200.ffff PCI A I/O space
148 * 1fe.0201.0000 - 1fe.0201.ffff PCI B I/O space
149 * 1ff.0000.0000 - 1ff.7fff.ffff PCI A memory space
150 * 1ff.8000.0000 - 1ff.ffff.ffff PCI B memory space
151 *
152 * NB: config and I/O space can use 1-4 byte accesses, not 8 byte
153 * accesses. Memory space can use any sized accesses.
154 *
155 * Note that the SUNW,sabre/SUNW,simba combinations found on the
156 * Ultra5 and Ultra10 machines uses slightly differrent addresses
157 * than the above. This is mostly due to the fact that the APB is
158 * a multi-function PCI device with two PCI bridges, and the U2P is
159 * two separate PCI bridges. It uses the same PCI configuration
160 * space, though the configuration header for each PCI bus is
161 * located differently due to the SUNW,simba PCI busses being
162 * function 0 and function 1 of the APB, whereas the Psycho's are
163 * each their own PCI device. The I/O and memory spaces are each
164 * split into 8 equally sized areas (8x2MB blocks for I/O space,
165 * and 8x512MB blocks for memory space). These are allocated in to
166 * either PCI A or PCI B, or neither in the APB's `I/O Address Map
167 * Register A/B' (0xde) and `Memory Address Map Register A/B' (0xdf)
168 * registers of each Simba. We must ensure that both of the
169 * following are correct (the prom should do this for us):
170 *
171 * (PCI A Memory Address Map) & (PCI B Memory Address Map) == 0
172 *
173 * (PCI A I/O Address Map) & (PCI B I/O Address Map) == 0
174 *
175 * 1fe.0100.0000 - 1fe.01ff.ffff PCI configuration space
176 * 1fe.0100.0800 - 1fe.0100.08ff PCI B configuration header
177 * 1fe.0100.0900 - 1fe.0100.09ff PCI A configuration header
178 * 1fe.0200.0000 - 1fe.02ff.ffff PCI I/O space (divided)
179 * 1ff.0000.0000 - 1ff.ffff.ffff PCI memory space (divided)
