of/lib: Allow scripts/dtc/libfdt to be used from kernel code 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 Signed-off-by: David Daney <david.daney@cavium.com> Cc: linux-mips@linux-mips.org Cc: devicetree-discuss@lists.ozlabs.org Cc: Grant Likely <grant.likely@secretlab.ca> Cc: linux-kernel@vger.kernel.org Acked-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 2012-07-05 16:12:38 +00:00			`#ifndef _LIBFDT_ENV_H`
