The idea is interesting; we have already thought about generating device trees in u-boot-v2 from the driver model. As u-boot-v2 has a module concept (think of it as in linux -> insmod plus EXPORT_SYMBOL), it would even be possible to change the driver model to device tree transformation by uploading a new module; this is necessary, as upstream maintainers tend to break oftree semantics with almost every kernel release - seems to be part of the design :-) However, no time to investigate this further atm. rsc -- Dipl.-Ing.
