I wonder, why many of the patches are also included in uClibc's
Buildroot then. Don't the avr32 users use Atmel's Buildroot? I'm an
avr32 user myself and only use Atmel's Buildroot for development. One
drawback is that I'm not up-to-date with uClibc, because these changes
are only seldom merged into the Atmel branches, only short before their
release candidates. So I end up working on another file base, which
doesn't ease integration of changes into uClibc's Buildroot. I could
merge myself, a branch "upstream" is available and is updated often, but
that doesn't make sense somehow. I haven't yet tried it, so I don't know
whether it will cause some hassle or not.

I haven't yet asked why this merge happens so rarely. Maybe lack of
time? OK, I'm already getting avr32-buildroot specific, but I think
updating the "devel" branch would be nice, even without testing
anything.  Currently the three branches "devel", "master" and
"atmel-2.3" are the same, pointing to the latest release.

Yes, mplayer for example is more than 2 years old and includes a huge
avr32 patch.
