Glad to hear from you again! I hope you have fully recovered!

I agree. I have also poured endless hours into Debian's sh4 port fixing
dozens of bugs myself and reporting them upstream whenever I couldn't
fix them myself.

I would also like to add that getting device tree support into SH would
be a huge leap forward and I would be happy to help with the efforts. I
still have some LANDISK and NextVoD devices available if anyone needs
hardware for testing and development, FWIW.

Would be great to also hear back from Sato-san, he is still active
on his other Linux trees [1].

And I'm still very much looking forward to these. I will certainly
buy a bunch of J32 to use them as buildds for Debian's sh4 port!

Thanks,
Adrian
