I'm not too familiar with barebox's defaultenv/defaultenv-2. Our work on
omap5 was based mostly on omap5 code from U-Boot and omap4 code from barebox.
Mostly, I used pcm049 as an example of omap4-based board in barebox. So
arch/arm/boards/omap5_sevm/env/config looks like this one, but includes
only most necessary thinks to load to barebox prompt.

Please, give me a hint, which board can be used as an example of using
defaultenv-2, maybe I'll do something.

We worked with OMAP5-based board, produced by Phytec (Phytec phyCORE-OMAP5),
but, as I have mentioned above, code was partially ported from U-Boot's
OMAP5-sevm board. I'll correct it.
