I have just been told on linux-rockchip mailing list that such a change
should not be done as /memory is being special-cased in dtc warnings for
the benefit of U-Boot. Supposedly U-Boot cannot handle updating memory
size on /memory at 0.

If that is untrue, please someone object on the Linux mailing lists.

Andreas
