I'm not up on 8xx, but it may not have been pulled forward into the "powerpc" architecture (still "ppc"). The "powerpc" architecture switch is where linux/u-boot started using the FDT.
8xx is supported in arch/powerpc.
Yes, I have add CONFIG_OF_LIBFDT and CONFIG_OF_BOARD_SETUP for the FDT support which is missing in U-Boot-v2009.08, and it works well, but I found none complete document on how to write a dts file and add special device in it.
Any tips? Thanks
See Documentation/powerpc/booting-without-of.txt, Documentation/powerpc/dts-bindings, and the ePAPR specification for information on the content of device trees.
