We'll really encourage people to look into that tree, it'ts really
amazing stuff. Next week we'll have a Technology Week with the
Pengutronix crew (only net, no phone :-) which will probably be used for
heavy u-boot-v2 hacking. So any ideas from the community are welcome!

I think this is the only sane maintenance strategy. We want to have a
clean tree, so anything which is ready for v2 must be reviewed anyway.

There's still an issue that the BF randomly hangs when "Uncompressing
kernel". Maybe the Analog people have an idea?

... which is a very cool feature. It is now possible to write extensions
to u-boot without having the old object files around.

We'd like to prepare a first numbered snapshot release during the tech
week, in order to have a well defined base for people to play with.
