Yes, I think I will eventually get around to it. For now the focus is
on getting the Linux kernel support into shape for upstream, however.
As I needed a convenient way to boot Linux on the device for this task
a Barebox port was the logical first step. ;) It may take a while until
I circle back to improve the Barebox support.

Forgot to mention: USB is also supported.
