    kbuild: centralize .dts->.dtb rule · 90b335fb
    Stephen Warren authored
    All architectures that use cmd_dtc do so in almost the same way. Create
    a central build rule to avoid duplication. The one difference is that
    most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather
    than building the .dtb in the same directory as the .dts file. This
    difference will be eliminated arch-by-arch in future patches.
    
    MIPS is the exception here; it already uses the exact same rule as the
    new common rule, so the duplicate is removed in this patch to avoid any
    conflict. arch/mips changes courtesy of Ralf Baechle.
    
    Update Documentation/kbuild to remove the explicit call to cmd_dtc from
    the example, now that the rule exists in a centralized location.
