Maybe not, but where it is we should be using that information. Absolute minimum we should be using the existing qdev address rather than inventing a new one. Duplicating this logic inside every device seems like a bad idea so I suggest identifying ram blocks by a (name, device) pair. For now we can allow a NULL device for system memory.
