Unfortunately, dtc requires a model:
$ dtc arch/powerpc/boot/dts/dbox2.dts
DTC: dts->dts on file "arch/powerpc/boot/dts/dbox2.dts"
ERROR: Missing "model" property in /

MTD handles this correctly. dbox2 uses "Flash without bootloader" for flashing
image updates and "Complete Flash" for creating a backup of everything.
OpenWRT also uses overlapping partitions BTW (and also for flashing updates).
