It assumes a different approach for getting memory to the ns side.
Initially bootstrap is configured to only uses a part of the memory so
that the other part can be used for the ns side. From the point of view
of the vmm this is 'iomem' because it's not ram. However, getting ram
for the vmm shall also work via a dataspace.
