    Just to make sure we're considering properly what this change means..

    Does this patch require using CONFIG_CMDLINE_FORCE for older bootloaders
    with the device tree append patch?

    Or should we still somehow get ATAG_CMDLINE let's say in the uncompress
    code and use that if nothing else is found?

    Otherwise booting old boards with the same kernel will be painful as
    it requires a kernel recompile to set the cmdline..

    Also, not counting the separate DT append issues, I got things booting
    with these patches (and the dts files) on omaps. So for patches 1 - 5,
    and patch 8:

    I don't have versatile or tegra, so can't test those :)
