Adding Catalin and Will for additional input as well, this is more their
area than ours.

I don't think we have formalized this as a policy, but we clearly don't
want new boards to use the spin table hack. As there are other
boards using psci on the same chip, I don't think this is a
hardware bug.

Matheus: can you explain what keeps you from fixing the
bootloader instead?
