Related question: I'm using a newer U-boot and managing the load of the
kernel and the device tree from separate partitions of my boot media.

Having the two partitions and managing the kernel and the tree
separately is a bit cumbersome, or maybe I'm just lazy. Regardless, can
I just use that "static" file name option when I build the kernel, load
the cuImage, and just invoke 

bootm <cuImageLoadAddress> ?

Will it work to just leave off the - <device tree Ram address>

I think I had it set-p right yesterday and I gave it a try, but no joy.

Can it be this simple to statically link the device tree with the kernel
build? For my application I don't see a benefit in keeping them separate
(the kernel and the tree).
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.
