From: Roland Vossen <rvossen@xxxxxxxxxxxx>
Driver now builds for big endian mips platform, possibly also for other
big endian platforms. A change was made to the R_REG and W_REG macro's.
These macro's perform an xor (^) operation for endianess swap purposes.
Gcc complained because an xor operation is not allowed on a pointer type.
Fixed this by casting the pointer to an unsigned long.
