+ Create flattend device tree blob object suitable for linking
+ into vmlinux. Device tree blobs linked into vmlinux are placed
+ in an init section in the image. Platform code *must* copy the
+ blob to non-init memory prior to calling unflatten_device_tree().
+
+ Example:
+ #arch/x86/platform/ce4100/Makefile
+ clean-files := *dtb.S
+
+ DTC_FLAGS := -p 1024
+ obj-y += foo.dtb.o
+
+ $(obj)/%.dtb: $(src)/%.dts
+ $(call cmd,dtc)
