When the MXC MMUC driver is used on a Freescale MPC512x machine, it contains some additional byteswapping code (I'm assuming this is a workaround for a hardware defect). This uses the ppc specific st_le32() function, but there's no reason not to use the generic swab32() function instead. gcc is capable of generating the efficient ppc byte-reversing load/store instructions without the arch-specific helper. This patch, therefore, switches to the generic byteswap routine.
