To clarify, I meant to enable this in the kernel.  It'll then take the
ATAGs passed from the bootloader (including RAM size), and modify the
dtb accordingly.  No bootloader modification necessary.

It's used as a stop-gap measure (including ARM_APPENDED_DTB) until
everyone is shipping devices with devicetree-aware bootloaders.
Primarily for developers and tinkerers.

See my comment above.  It's a lot less work ;-)

hth,
