It was pure chance that the first two MIPS system to which we  ported
U-Boot  (INCA-IP and Purple) happened to be big endian. We, too, have
LE MIPS systems in the queue.

Please feel free to go on :-)

Yes, but please not not break backward compatibility.

It's true that newer tools are available and working fine,  but  that
doesn't  mean  that we can brak support for the old toolchains. There
are many projects running in Big Companies wheare introducing  a  new
toolchain is sinply not possible with reasonable efforts.

Yes, this is correct, at least with the  current  code.  Please  feel
free to improve that.
