The kernel raw nand API has seen some significant changes recently. It
looks like the kernel marvell_nand driver relies on newer API. I'm not
sure how easy would be syncing the drivers to a degree that makes
porting of changes trivial. It would probably require many other changes
in generic U-Boot raw NAND code.

Maybe Miquel can shed some light on that.

Unfortunately, the U-Boot MAINTAINERS NAND FLASH entry is marked
"Orphaned (Since 2018-07)".
