I have some landisks. Is there a sane u-boot for them?

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, Daniel
