    of/lib: Allow scripts/dtc/libfdt to be used from kernel code · ab253839
    David Daney authored
    libfdt is part of the device tree support in scripts/dtc/libfdt.  For
    some platforms that use the Device Tree, we want to be able to edit
    the flattened device tree form.
    We don't want to burden kernel builds that do not require it, so we
    gate compilation of libfdt files with CONFIG_LIBFDT.  So if it is
    needed, you need to do this in your Kconfig:
    	select LIBFDT
    And in the Makefile of the code using libfdt something like:
    ccflags-y := -I$(src)/../../../scripts/dtc/libfdt
