Your erizo barebox/qemu work made the initial iterations much quicker,
so thanks for that!

Sure. I'll send out a v2 and send you a github link later today or early tomorrow.

This is becoming relevant for us as well as we'' port barebox to the
BeagleV. Our intention is to get the other Qemu platforms running
as well in preparation for actual hardware support.

Thanks for the heads up. I will take a look at your rebased branches,
once they are available.

Sascha just picked it up.
