The problem is here:

This adds a partition in order to read the barebox image from it. You already
have a partitioned device, so we can't create any conflicting partitions.
We could read from that partition instead of re-creating it, but likely the
partitions do not exist in all cases. You could try the following patch. It's
completely untested, but the idea is to read from the raw device
instead.
