It's ok from Hilscher side. I've talked to our CEO and he is fine with
dropping it. Those boards are not produced anymore and our new Asics
(e.g. netX4000 and upcoming) will replace netX100/500 in the long term.
Our Asics usually have a guaranteed lifecycle of 10 years and netX100
has been around since 2006, if I remember correctly, so we don't expect
many new linux projects arising, with the need for the newest kernel.
Old kernel version will still be working though.

We want to work with the community now and in the future, but for
netX4000 we first needed to get this SoC working. It took many
development cycles to get all implementation working and now it seems to
have settled so we can think about step two. netX4000 Final (with all
required changes) was released end of last year.

Main problem would have been the continuous change of the Asic during
development and more or less constant changes to kernel sources. I think
this would have caused some laughing on the mailing list if we submit a
patch one day and do it the complete other way round with the next
(possibly non-public) stepping of the Asic. But probably that's just my
personal feeling.

Thanks for all your valuable input. I will take a look an see what I can
do about it.


Mit freundlichen Grüßen / Best regards

Michael Trensch
