FWIW, I managed to install my clearfog-base using it, though I don't
remember any particularly bad corner case. I remember about the usual
issue with the SPL being a bit too verbose and breaking the upload but
that's something that already affected prior versions. I think the
current u-boot version had a pause at this moment but I could be wrong,
anyway it used to work for me.

Just my two cents,
