Wolfgang,
I don't want to be annoying, but if you're going to apply this patch, I think it needs to be applied now. There's a patch for the device tree compiler (DTC) that updates it to version 17, which claims to be compatible with V16. Soon, we're going to have V3, V16, and V16 DTBs flying around, so U-Boot needs to make a stand on what it considers compatible and what it doesn't.
