That seems like something that can be done first, so that at least
there's a way to have Renesas TF-A + U-Boot mainline to work together.

That would be the ideal but it will take more time, so starting by
option 1. would at least cover the transition period.

I can propose a patch on Renesas TF-A to pass a DTB blob on the RZG2L
platform as well. From the snippet you sent me, it looks like you may
have one ready somewhere though?

Thanks,

Mathieu
