Ok, but then bNumConfigurations would be set to 2 as well?

Ok.

Sorry. No, I wasn't very clear. We used U-Boot based on 
2011.09_AM335xPSP_04.06.00.08 from arago-project. But know I cannot 
find the patches on arago-project.org. If you want I can provide these 
patches to you. But, we're sticking now to v2013.07 anyway.
