by rman_get_virtual(9) to access device registers sparc64 currently cares about. Ideally ata(4) should just be converted to access these using bus_space(9) read/write functions instead as there's really no reason to do it the former way. However, this part of ata-siliconimage.c should go away in favor of siis(4) sooner or later anyway and I don't have the hardware to actually test the SX4 bits of ata-promise.c. Also ideally the other architectures should also properly handle the BUS_SPACE_MAP_LINEAR flag of bus_space_map(9) so this code wouldn't need to be #ifdef'ed.
