This new option allows U-Boot to embed a binary device tree into its image to allow run-time control of peripherals. This device tree is for U-Boot's own use and is not necessarily the same one as is passed to the kernel.

Couldn't that just be:
$(CPP) -P $(DTS_CPPFLAGS) $< >$@.tmp
- $(DTC) -R 4 -p 0x1000 -O dtb -o ${DT_BIN} $@.tmp
- rm $@.tmp
I did have that originally, but got this warning:
armv7a-cros-linux-gnueabi-gcc.real: warning: /home/sjg/trunk/src/third_party/u-boot/files/board/nvidia/dts/seaboard.dts: linker input file unused because linking not done
so I fell back to doing as I have done. I think it might be because gcc normally assumes that anything it cannot understand must be a link script.
Regards, Simon
