A quick update on this, Stephen Warren (nvidia) has posted an updated
version of your "config: introduce a generic $bootcmd", and that just
got Acked, so hopefully that will make it into v2014.10:

It would be nice to also sunxi converted to this upstream.

This means that you need to post a conversion patch this weekend
the latest, otherwise it will be too late for the freeze (freezes
in u-boot are based on the posting of v1 of a patch).

I can try to do this myself this weekend, but chances are that
I won't have time for this.

Regards,

Hans
