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.
