No. It does have a well defined address map that pretty
strongly suggests that you ought to have flash and RAM
at certain addresses, but the flash and RAM are not part
of the CPU core itself.

(Bitbanding, on the other hand, is part of the CPU core
and the memory region setup for it should stay in this
function.)

Agreed.
