You need to define a dts file (see the existing ones in 
arch/powerpc/boot/dts for examples), and set CONFIG_DEVICE_TREE to tell 
the wrapper which one to include.

Note that this dts must have linux,network-index properties in the 
network nodes for the MAC addresses to be filled in, and must have 
/chosen/linux,stdout-path if you want output from the wrapper (useful if 
something goes wrong (such as insufficient memory to relocate the 
kernel) or if you want to edit the command line).

You also need to do make zImage rather than make uImage for cuImage to 
be built.
