This is a view of the world which is becoming steadily less
true. It is not possible to configure a hardware A9MP without
the GIC and internal peripherals, for example. And the A15's
timer peripherals are accessed as cp15 registers, not memory
mapped I/O, making them even more obviously a coherent part
of the CPU.
