Well, last time I checked, I didn't experience any particular problem with mainline U-Boot and sunxi-3.4 on sun5i/A13 but I probably lack context on this. > Combined with Tsvetan's lack of any sign of response or any indications > that anyone else could be interested, I don't feel very much motivated > to do the "communication" part of the job, which is required to clarify > the status of these 3.4 branches and move them forward. Still, I would be interested in having a sunxi-3.4 branch that can actually be used on all the supported chips and devices. > > I have been trying to boot sunxi-3.4 on sun7i/A20 using upstream U-Boot, > > with no success.

Well, it doesn't fit every use case yet and I will (sadly) have to use sunxi-3.4 for Replicant, so I need something that actually works.
