This sounds very good.

Could you help us decide what goes into u-boot? My heuristic for this
proposal: It's much better if you decide it than if I do it :-)

Let's not worry about the repository/permissions now. I could just
apply the patches you (and perhaps someone else) say are OK and if the
volume of patches somehow grows we can use GIT as a DCVS or something
to make things easier. Later we would find a way to create the
snapshots or we can link to the snapshots compiled and tested by

Any cons?

Werner, what do you think about the U-boot patches and about the idea
in this email?
