I find this confusing, perhaps due to overloading of the word "register".
Aren't CP15's a class of coprocessor _registers_? Could it perhaps be clearer
to talk about memory-mapped versus CP15-mapped timers?

Is "soc" documented somewhere or is it just a name for a container? Assuming
the latter, it's not obvious to me why being a child of a system on chip node
would imply having memory mapped registers.

Thanks,
Christopher
