Why do we have to wait for so long? The next U-Boot MW is about two months away from now. And with U-Boot's usage of the DT we can surely minimise the risk of breaking something, by just reviewing that the DT changes do not touch or interfere with any devices that U-Boot cares about.
This way we can get up-to-date DTs now (which UEFI boot benefits from), so that users don't have to provide "their own" DTs.

Cheers,
Andre.
