That's a bug somewhere, the device tree should describe the hardware,
and not necessarily the massaged format that the kernel wants it in to
not trigger a bug.

So I don't want to see this patch merged, I want to see a proper fix
instead, please.

There are also already other exynos platforms and device trees with
more than 256MB in the memory node. Changing all of them this way
seems unreasonable.
