You will need the to be released FW version 3.06.xx or above. This new
FW won't be official release until at least a few months. If you want
to test this new firmware, we can get you an earlier image but there
will be very limited support. Though, Hoan will support you when
possible.

This can only get pull into xgene-next if it had accepted upstream.
