I see, error on my end then. I will start building sandbox for the USB tree.
Thank you for pointing this out! This also stresses my point that U-Boot project
does need a proper CI (which we could have had thanks to Vadim, but we didn't
persudate that, dang again).

I think this CI stuff should be added to the agenda of the U-Boot minisummit 
discussion.

Another point to the CI discussion could be that we could prepare a docker image
with all the toolchains preinstalled, so one can run buildman easily in a well 
defined environment on his/her own.

Best regards,
