The only difference I found is that at the 0x0 we have ROM for the first and SRAM for the latter. 

As you said to build the hardware as it is it hard to get the exact size/address of Flash and RAM or the range of them which I think is the main issue.

The rule of thumb is: model what the real hardware does.
If that means "we have one mapping at boot time and then
at runtime there's some register that changes the mapping",
then model that.

That said, sometimes if the two maps are very similar, or if
in fact you know the guest you care about never does whatever
the thing is to change the memory map, then you can get away
with only modelling one of them.
