I wasn't aware that the Warp and Sam440EP disallowed LE mode - I'll
definitely unwire them and move the ARCH_SUPPORTS_LITTLE_ENDIAN to just
the sub-arch's that support it.

As for the other boards, I would like to wire them up if they are able
to support LE mode - If anyone has one handy I would love to hear if
they are able to begin booting a LE kernel with these patches, or when &
how they fail.

Cheers,
-Ian
