MIPS32 4Kc CPU board, with support for the MIPS64 5Kc and the QED RM5261 CPU boards to follow. The cs4281 audio hasn't been tested, there are some interrupt problems with onboard the pciide, but all other on-board peripherals work. The evbmips port will support more MIPS evaluation boards in the future.
