Marcel Moolenaar de2fa7b8af Redefine bus_space_tag_t on PowerPC from a 32-bit integral to ... a pointer to struct bus_space. The structure contains function pointers that do the actual bus space access. The reason for this change is that previously all bus space accesses were little endian (i.e. had an explicit byte-swap for multi-byte accesses), because all busses on Macs are little endian. The upcoming support for Book E, and in particular the E500 core, requires support for big-endian busses because all embedded peripherals are in the native byte-order. With this change, there's no distinction between I/O port space and memory mapped I/O. PowerPC doesn't have I/O port space. Busses assign tags based on the byte-order only. For that purpose, two global structures exist (bs_be_tag and bs_le_tag), of which the address can be taken to get a valid tag. Obtained from: Juniper, Semihalf		2007-12-19 18:00:50 +00:00
