I recently rewrote the endianes selection in the Kconfig menus.  The
individual platforms will now have to explicitly select
which endianess they support.  I know that Alchemy supports big endian
operation in hardware but no idea if all the Linux code is working
properly, so I've been conservative and choose to limit the system
to little endian until somebody reports big endianess support to be
actually working.
