The u-boot repository have now followed and been moved to
linux-sunxi/u-boot-sunxi. This repository is the stable
distributionpoint for sunxi u-boot.
git:
https://github.com/linux-sunxi/u-boot-sunxi.git
wiki:
https://github.com/linux-sunxi/u-boot-sunxi/wiki
The old repository continues to live on for now as my personal
development repository, but I guarantee that I will continue to break
things there just as I have done in the past. If you want something that
runs then make sure to use linux-sunxi/u-boot-sunxi repository.

Henrik
