Well, tell me that it is wrong, but isn't it common community
methodology to have rebasable things like patch stacks or git trees
against mainline instead of disconnected vendor trees?

You didn't explain how for example your trunk [1] is related to mainline
[2].

We use mainline linux and u-boot-v2, which is surely not what ADI
supplies officially to their random commercial customers. Nevertheless,
it is the way community technology works elsewhere.

Hmm, the sources are here: http://www.section5.ch/dsp/icebear/bfloader-1.2.tgz

Do you have a good hint for a better low level debug tool? For all other
processors like ARM, PowerPC and ColdFire we use a BDI2000, but it seems
not to be available for blackfin.

Thanks for the constructive comments.

"Trust us, we are $BIG_VENDOR" is not the way these things are usually
done. Sorry, I don't buy this. Chip vendors just too often lose interest
in supporting their users once they have moved to the next generations
of chips or whatever.

Can you explain why bfin should not have gcc.gnu.org as it's upstream?
