It's not that "we" don't want to allow building this on non-PPC per se,
but making it build requires some surgery that I think should be done by
whoever might eventually want it. So _my_ reason for lowering this
dependency from QUICC_ENGINE to UCC_GETH is exactly what it says above.

Well, that kind of thing is impossible to know for outsiders like me.
Maybe one can amend the commit log with that info:

"Also, the QE Ethernet has never been integrated on any non-PowerPC SoC
and most likely will not be in the future."
