Ok > Is there any conversion to DT you can easily point at as an example of > the kinds of changes needed? Robert Jarzmik and Daniel Mack worked on the conversion of the PXA platform to DT. Daniel contributed the port for Raumfeld, which should be complete, while Robert worked on more driver conversions and mentioned[1] that he had converted additional boards in the past but did not merge it upstream. They can probably point you to whatever is missing. I would expect the generic PXA drivers (spi, mmc, nand, i2c, audio, fb, gpio, keypad) to basically work work a correct DT description, while the machine specific drivers (scoop and pcmcia mainly) will need DT support in the driver. In addition, Linus Walleij and Marc Zyngier have both expressed interest in keeping sa1100 (h3600, collie, assabet, jornada720) alive, but those don't have any DT support yet and require much more work. Also note that while you can now build a kernel that includes support for all little-endian ARMv4T and ARMv5 machines, StrongARM machine still require a separate kernel build.
