Yes, you can use cuImage to bundle the device tree with the kernel (note 
that the type of image you use *must* match the type of bootm command 
you use), though it's not recommended if you have a u-boot that can 
properly pass a device tree.  cuImage relies on the bd_t to get 
information from u-boot, and this is a very fragile structure, and 
contains less information than the device tree.
