I guess we should look at how TF-A expects this to work in
real-hardware setups. Presumably the idea is that TF-A
carves out the RAM it wants to use for the RMM and
modifies the device tree / ACPI tables accordingly ?

Also, are we going to want to have more link properties
for the board to be able to pass in MemoryRegions corresponding
to the different physical address spaces, the way we do
today for Secure vs NonSecure ? Or do we think we can
create suitable board models with "just" a lot of MMUs?
