- Store the OpenFirmware "reg" property in the macio ivars. - Use a struct to define the structure of a "reg" property entry. - Discover all memory ranges, not just the first. - In ata_macio, manage our own range and hand out our own allocations using bus_space_subregion. - Fix bus_space_subregion to handle subregions of sparse maps.
