They probably have a ROM (which should be the real "-machine
firmware=...") that loads firmware from NAND flash ("-drive
if=mtd,file=...") into RAM, and then gets out of the way.

Perhaps it's what QEMU should do, but not even the few machines that
support "-drive if=mtd" do it to this level of accuracy.
