Either I don't follow or you don't get Arnd's comment...

IIRC, his suggestion which I agree with was to remove the memory-region
phandle and just move all the properties into the reserved memory node
directly. This simplifies things such that we are just describing
properties of a chunk of memory rather than a Linux specific node for
virtual driver.
