The uboot version can't be more than 1.1.6, the linux must be if you're going to go from a Jan. 2005 u-boot to a Nov. 2006 u-boot, looking to boot an Oct. 2008 kernel, why not just go all the way to the present versions on both? > 2.6.27, and I can't find the information if it's compatible. > > Can anybody affirm me if it's possible, and how to do it in linux 1.1.4 ? > > How do we change the bdinfo structure header to device tree, is there any > board which uses this feature ? if you really cannot update u-boot, try making a linux cuImage for your board; it contains a wrapper that combines the device tree and bdinfo, then boots the linux kernel proper. as a guide, see e.g., the ep8248e dts in linux-2.6/arch/powerpc/boot/dts, and corresponding platform code in linux-2.6/arch/powerpc/platforms/82xx. please also consider submitting patches for your board to both upstream projects, so this problem doesn't occur again in the future.
