+On IXP4XX systems the FIS directory is big endian even with a little
+endian kernel. This patch recognises the FIS directory on such a
+system and byte swaps it to obtain a valid table based on the 'size'
+field of the FIS directory (the size field is know to always match the
+erase block size on such systems, and probably all systems.)
