So this means that the Barebox build is OK, and only the genimage part
is causing problems. But this doesn't prevent from merging the barebox
aspects of the series (patches 1 to 6), which are really the important
part. The last patch is really more a defconfig proving that it works,
I am not even sure that in practice we want to merge a defconfig for
BeagleBone that is just different from beaglebone_defconfig in the fact
that it uses Barebox instead of U-Boot. Peter?

Peter, I think you looked at using genimage on AM335x, what were your
conclusion? On OMAP3, there were some very strict geometry restrictions
in the romcode, but I don't remember if your conclusion is that they
also apply to AM335x or not.
