What is the benefit of this yet-another NIH protocol compared to ie. DFU/UMS/Thor/Fastboot ?
This is mostly used on Rockchip chipset. All the rockchip SoC boot rom and develop tools implement this protocol. So we want to use the same protocol which compatible with current tools.
This does not really answer my question. We have protocols which implement exactly this functionality already, why do we need another one ?
I think the point is that this is widely used with Rockchip devices, and for mainline U-Boot to be fully useful it needs to support it.
OK, I'll leave that decision to Lukasz . I'm not a big fan of adding redundant functionality only because someone thought NIH is good before looking at standards.
However I do think it would be good to move to using DFU etc. if possible?
Yes.
