This is subject to speculation. David Illies, our TI field application
engineer, keeps telling us that 3.2 will be supported "eventually". I
personally don't think they ever will - the commit history in their
public git does not look like anyone is doing any portage work. Plus
3.2, the version they keep mentioning, is starting to smell oldish as
well. I would very much like to see support for dm81xx in something
_current_, but it's unrealistic given previous experiences with TI.

Thanks, looks like I'll need it :)  By the way, we successfully pulled
gcc-4.5 in our layer and are building with gcc-4.5 on angstrom-v2012.x
right now. Since you're on 8148 as well, and in case you would like to
stay up-to-date on what we're doing, just check
https://github.com/DFE/HidaV from time to time.

Regards,
Thilo
