vexpress-a15 allows up to 30GB (assuming a 64-bit host system;
32-bit hosts are always limited to just under 2GB guest RAM).
The "virtual machine" board 'virt' can also handle up to 30GB.
highbank and midway can do 4GB.

It's just a reflection of which SoCs and boards we've modelled.

You have to read the source code, I'm afraid.
