As far as I can tell, no other platform unregisters and re-registers memory at reset, so that is a difference between reset and boot. Maybe I don't understand your other question. Before qemu_system_reset() was called at initialization time, memory was not unregistered, and therefore the platform had memory and could boot. -Hollis
