    Kbuild: Use dtc's -d (dependency) option · 7c431851
    Stephen Warren authored
    This hooks dtc into Kbuild's dependency system.
    
    Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only
    tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous
    lack of this feature recently caused me to have very confusing "git
    bisect" results.
    
    For ARM, it's obvious what to add to $(targets). I'm not familiar enough
    with other architectures to know what to add there. Powerpc appears to
    already add various .dtb files into $(targets), but the other archs may
    need something added to $(targets) to work.
