The implementation only allows for the two registers to be up to a
32-bit address space apart, but it allows for the base of the device to
be at any part of the target's physical address space. It's not
unreasonable IMO. If you think it is, then I can reduce it to uint32_t
but that loses semantic information regarding the base address (that it
is physical).
