Hmm, I also noticed that this enables support for both the Cortex-A9
(using GIC and L2X0) and the PJ4 based variants of Armada 1500. I
wonder if we should have separate options for the two. E.g. if you
want to build a kernel for the Chromecast, there would be no need to
enabled PJ4 support.

I have not been able to find out which core is used in most of the
production Google TV boxes.
