Oh good.  I was hoping someone would get a chance to do this.  I had a
few more ideas about what might have been needed but haven't been able
to cycle back around to hooking mine up and playing again.

Currently it falls under Albert's care as the overall core ARM
maintainer.

I think the overall answer here is that as the code base and
implementation evolves everywhere, we'll need some adjustments to match
up.  Please make sure to keep York Sun in the loop too as Freescale is
active in this area as well (and the other Freescale folks too as they
transition from multi-core PowerPC to multi-core ARMv8 :)).  Thanks!
