amazing!! :D Having serial console work with the stock kernel from Debian will
make it so much easier to test and fix other stuff like debian-installer early
on. Thank you! :)

Yes, LCD support is part of the remaining patches:

I also saw your message in #mnt-reform yesterday and you are right, my script
sets console=ttymxc1 instead of console=ttymxc0. This is due to a wrong commit
from my end because my S1 (ttymxc0) port has a non-functional TX pin so I was
always using S2 (ttymxc1) to talk with my reform. Fixed here:

Thanks again!

cheers, josch
