I didn't see this. So it seems like for now just adding
CONFIG_YMODEM_SUPPORT, making that select CONFIG_CRC16 and the
Makefile tweak would be enough for now.

Would that be acceptable for now? It seems like the xyzmodem thing
needs a bit of refactoring etc. I actually have an almost entirely
rewritten version of it somewhere that I wrote because of the issues
in the current version. I'd prefer to fix the build issue for now and
refactor + replace most of the code when I have time to do it
properly.

Thanks,

Daniel
