This is indeed not the case. Open Firmware  is another type of boot
loader with a Forth based programming interface, see
http://en.wikipedia.org/wiki/Open_firmware

You can boot device-tree enabled Linux kernel images with old (not
device-tree aware) versions of U-Boot by using the cuimage format (but
updating your code and use current versions of U-Boot is of course
strongly recommended).

Just use current code, i. e. latest released version or top of tree
from the repository.
