A7/A15's SCUs are CP15 devices, not memory mapped ones. The same with
timers - A9-like TWD is no more, "taken over" by architected timers.
It's a different initialisation and SMP code, essentially. I wish it
wasn't... Also, in future I may be working on adding support for
MMU-less R-Class processors, which are going to be very very
different ;-)

Cheers!
