Maciej W. Rozycki b2e68aa337 [PATCH] defxx: Big-endian hosts support 
The PDQ DMA engine requires a different byte-swapping mode for big-endian
hosts; also the MAC address which is read from a register through PIO has
to be byte-swapped.  These changes have been verified with DEFPA-DC (PCI)
boards and a Broadcom BCM91250A (MIPS CPU based) host.
