You'll need to replace u-boot with custom one that is able to deal with dts. There are 2 ways ATM - use bootm dts approach, which could load device tree from external source, and built-in that makes in compiled into u-boot. Both patches against u-boot should be searched in u-boot mailing list archives. For 83xx both way work just fine. -- Sincerely, Vitaly
