Max out system memory by default
Set the system memory to 2MiB base, 2MiB ext. This is a fully loaded 3B1
motherboard with a RAM expansion board. 512KiB base/no ext is the minimum
which can be specified (e.g. kernel memory map area only) but does not leave
any room for userspace. The kernel doesn't like that and doesn't handle it
gracefully...!
