Can we get rid of this? I think I remember some discussion about the same
topic going on the linux-tegra/devicetree mailing lists, where it was decided
that /mem-reserve/ entries should be dropped until some driver in the
mainline kernel was actually going to use this memory. Perhaps U-Boot should
take the same approach.
