I think my submitted patch was a bit too invasive by removing most of
the environment, and have reworked the patch to leave much of the
environment:

  https://anonscm.debian.org/cgit/collab-maint/u-boot.git/tree/debian/patches/wandboard/config_distro_bootcmd.patch?h=experimental-2015.04

I haven't yet reworked it for resubmission, but I'd be happy to do so.

I was hoping to see the wandboard SPL support added before reworking, as
that will require a few minor changes to the config_distro_bootcmd patch
as well:

It would be nice if switching to config_distro_bootcmd.h was not
dependent on sorting out the console variable switch... though I'd be
fine with switching the default console to include the baudrate as well.

Thanks for testing!
