It took me approx. 4 hours to factor out the code and make a proof-of-concept FDT support for a little-endian ARM platform. ;-) (The device tree was only describing a cpu and a nor flash, though.

I never got around to clean it up and send though, but for sure, there is absolutely no reason to duplicate the code across the platforms.
