You could but do you really need it? The guest memory map is pretty much
static apart from RAM size and in the next version of my "xen: arm:
64-bit guest support and domU FDT autogeneration" series all the
relevant #defines should be available to the toolstack as well as the
hypervisor (and if not, we can fix that).

Any get/set memory map calls can be deferred until there is a need for a
more dynamic guest layout IMHO.

Ian.
