Adding device tree support to U-Boot

Hi all,

the U-Boot used by NVIDIA/Jetpack already has partial support for FDT and I guess it should not require too much work to extend it to be able to use device tree overlay files. I am thinking about implementing this since we have different image sensors and creating deploy images for all those sensors is tedious.

Has anyone here already done some work on this topic? Are others also interested in this feature and willing to collaborate?

I know that this will have some limitations (like not working on AGX Xavier as there is no U-Boot there) but it would still be a big improvement over the current situation.
