I have some landisks. Is there a sane u-boot for them? I think mine
still have the hacked up lilo thing.

This sounds like a fun project. I'm not sure if I could manage it
without the Hitachi/Renesas debugging dongle though.

Anyhow, it would be a shame to remove the ecovec just because it
doesn't have DT as it pretty much fully works with a few small patches
to fix some bit rot like ethernet and the LCD not working.
I sent a patch a few years ago for the ethernet and never got a response. :(

Cheers,
