Tim,

I have it building successfully now, and it loads over USB. I had to
disable BD718x7 PMIC children binding which required a small change to
the PMIC driver [1].  I then removed HS400, HS200 and UHS support in
SPL.  Once I did all that, the code size fit into SPL space.

I'll try to push my patch today or tomorrow.  I was doing some other
clean-up, but I might just push that as a small series in itself.
