If I recall correctly some of the MIPS chips had/ve an endian selector bit
on each page table entry in the MMU. The idea was to map each of the I/O
devices through the MMU and let that bit help in talking to the hardware
(i.e. Intel peripherals expecting little endian and motorola chips wanting
the opposite.)
