Including as it is creates two device_type="memory" nodes, one with
regs=<0 0>, which is definitely wrong.

The "memory at address" node name is in my opinion perfectly legal - p. 3.4
of the DT spec says "The name component of the node name (see 2.2.1)
shall be memory.". So the decompressor code may be wrong in looking for
adress-less "memory" node...

One way or the other, I'll get this fixed.

Thanks for letting me know!
