It's based on commit fe8e6d0b0e601ca0a63fe768d4b812d5a45a9da7 "arm/dt: Add dtb make rule" from Rob Herring.
With 'make ARCH=arm dtb', it builds Device Tree Blobs for those platforms enabled by CONFIG.

This patch works against Linaro kernel tree. But it needs to go through mainline review before it gets applied.

And now this file has to be touched for every platform added. Perhaps this can pick-up the dts name from Makefile.boot. Although Makefile.boot could possibly be removed on some platforms.
I was following the way that powerpc does similar thing. But yes, your suggestion looks saner in terms of keeping arch/arm/boot/Makefile clean. I would incorporate it in v2.
Thanks for the comment.
