From ab25383983fb8d7786696f5371e75e79c3e9a405 Mon Sep 17 00:00:00 2001 From: David Daney Date: Thu, 5 Jul 2012 18:12:38 +0200 Subject: 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$(src)/../../../scripts/dtc/libfdt Signed-off-by: David Daney Cc: linux-mips@linux-mips.org Cc: devicetree-discuss@lists.ozlabs.org Cc: Grant Likely Cc: linux-kernel@vger.kernel.org Acked-by: Rob Herring Signed-off-by: Ralf Baechle --- lib/Makefile | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'lib/Makefile') diff --git a/lib/Makefile b/lib/Makefile index 8c31a0cb75e..2f2be5a8734 100644 --- a/lib/Makefile +++ b/lib/Makefile @@ -130,6 +130,11 @@ obj-$(CONFIG_GENERIC_STRNLEN_USER) += strnlen_user.o obj-$(CONFIG_STMP_DEVICE) += stmp_device.o +libfdt_files = fdt.o fdt_ro.o fdt_wip.o fdt_rw.o fdt_sw.o fdt_strerror.o +$(foreach file, $(libfdt_files), \ + $(eval CFLAGS_$(file) = -I$(src)/../scripts/dtc/libfdt)) +lib-$(CONFIG_LIBFDT) += $(libfdt_files) + hostprogs-y := gen_crc32table clean-files := crc32table.h -- cgit v1.2.3-18-g5258
