please read linux/Documentation/powerpc/booting-without-of.txt To get a cuImage, you - need to adjust your <platform>.dts and configure your kernel to use it. - need the latest dtc (device tree compiler), - need the latest mkimage (from the latest u-boot tree) - and build your cuImage by building the target zImage (make zImage) -> your cuImage then rests in i.e. arch/powerpc/boot/cuImage.<platform> Aside of no good documentation, I ran into the problem that the embedded device tree doesn't get updated by the bd_t struct properly (the mac addresses) in the latest versions of the kernel. This might be a bug or a configuration error on my side. I didn't check yet. U-Boot with full device tree support will hopfully fix that, when it's out.
