Pushing stuff into mainstream is always desirable.
I don't mean to have AVR32 specific things out of uclibc-buildroot. Of
course it should be supported there as well. But mplayer is just a good
example, where support for it is wrong and is a good reason for a
separate AVR32 repo, especially given that it's well supported by Atmel.

But when you already put so much stuff into uclibc-buildroot to fully
support AVR32, what's then remaining in HCE's tree and for what reason
this is not put into upstream? With your arguments, HCE doesn't need to
commit to his own repository at all, he could just commit everything
to upstream. The only purpose of his tree then would be having stable
and tested AVR32 releases for the customers.

What's wrong with that? What would they want to commit? You also cannot
commit directly to Haavards avr32-linux repo. Do you then ask Linus for
push access because of that? Is this also the reason why you put all the
U-Boot patches into buildroot, because you don't have commit access to
the u-boot repo but to uclibc-buildroot?

I think if you have AVR32 changes, that shouln't go into
uclibc-buildroot, then you could always send a patch to the
avr32-buildroot mailing list or HCE.

I don't get it. You can use the HCE's git repo and just pull the updates
or rebase against it. What has this to do with the fact that you cannot
commit to the public repo?

No, I don't think nobody is using them, that was just expressed
unluckily. But it seems as if the AVR32 users that are subscribed to
buildroot at uclibc.org aren't using it. At least I got that feeling while
following this mailing list.

When I'm on stable, I definetly want to be on stable and only update/fix
packages that caused bugs. Consider a package that doesn't update its
version in buildroot (and also upstream maybe) during several months. It
will never FREEZE and always stay in development phase, because it's the
latest version, and it will probably get more patches.
So when merging the latest buildroot updates into my personal buildroot
repo for a board in development, I'd get changes behind my back also for
a released board in support phase.

So I will keep using branches in git instead of relying on buildroot to
include half a VCS functionality.
