[PATCH 2/2] Add MIPS arch support to barebox

[Shinya Kuribayashi]

Thanks Jean for bringing up old stuff :-), and nice to see the first
(workable) MIPS port of barebox this time, Antony.

Not at all, unfortunately.

I didn't care about code size, complexity, workable or not (ok, this is
important) when I was working on it.  What did care about is its boot
design.Having a glance at your head.S, compute_offset part looks good.
That's a part of what I have in mind, and implemented as ADR macro in
my prototype.

I'll write a lot more some other day.
