From 63b4b5bae52e48528876e13e858ef934ac2e4a3b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 2 Jun 2014 22:04:50 -0600 Subject: fdt: Add DEV_TREE_BIN option to specify a device tree binary file In some cases, an externally-built device tree binary is required to be attached to U-Boot. An example is when using image signing, since in that case the .dtb file must include the public keys. Add a DEV_TREE_BIN option to the Makefile, and update the documentation. Usage is something like: make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb Signed-off-by: Simon Glass --- dts/Makefile | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'dts/Makefile') diff --git a/dts/Makefile b/dts/Makefile index 3fca5f5c2f..f344efe64b 100644 --- a/dts/Makefile +++ b/dts/Makefile @@ -12,7 +12,11 @@ ifeq ($(DEVICE_TREE),) DEVICE_TREE := unset endif +ifneq ($(DEV_TREE_BIN),) +DTB := $(DEV_TREE_BIN) +else DTB := arch/$(ARCH)/dts/$(DEVICE_TREE).dtb +endif $(obj)/dt.dtb: $(DTB) FORCE $(call if_changed,shipped) -- cgit v1.2.1
