It's a relatively new target in the arch/powerpc/boot/Makefile which
wraps your compressed kernel and bootcode together with a device tree
blob. A device tree blob is created using a device tree source (dts).

A device tree source is plain text. Look inside arch/powerpc/boot/dts.
A device tree is essential if you want to boot an ARCH=powerpc
Linux-Kernel. Read this:

I supposed you were using 2.6.26 or 2.6.27-rcX
