Not that I know of. I must admit, I'm new to this codebase and so I'm
mostly looking at what code already exists and what the Rockchip fork
does to try and synthesize a solution. The Rockchip fork reads this
info, and it was a simple change, so that felt like the right path.

Oh, fantastic! I started working on this as a way to learn my way
around U-boot, but I've been learning that adding RK3506 support might
have been ambitious. What I have boots just fine and I learned a lot,
but... more experience here is definitely for the best.

(Your link [2] to your rk3506 branch is a 403 for me. Is that temporary,
or..?)

I'm happy to either continue with these patches if they seem useful
for any other reason, or to drop them if not. RK3506 is the only
reason I had for them myself.

Thanks,
