My only concern is from when I did:
https://patchwork.ozlabs.org/project/uboot/patch/20211224165704.2855211-1-trini@konsulko.com/
so I think you need to also drop the "imply OF_HAS_PRIOR_STAGE" from the
Kconfig files and should probably move to select (do not allow the user
to override this, it shall always be OF_EMBED now), or at least imply
(sufficiently advanced users may want a different choice and should be
able to make it).
