Tom,

I'm OK with you adding these patches to u-boot-tegra/master and sending
a pull request for that. Just please put these patches before any that
actually enable CONFIG_OF_CONTROL for any boards, so there's never a
window of broken commits.

I think it'd be nice at this stage to also drop the commit that turns
Ventana into a DT board, since re-using the Seaboard .dts file for
Ventana isn't correct. However, IIRC that commit was added to WAR some
build issue with Simon's patch series? If that's still a problem, then
I'm OK with converting Ventana if we have to, but we'll need to be very
careful that tegra-seaboard.dts doesn't add stuff that'll fail on, or
damage, Ventana.
