The DTB is appended to the zImage file.  You then need to convert the 
product of the concatenation to uImage format.

instead of this:

something like this is what you need to do instead:

$ cat arch/arm/boot/zImage arch/arm/boot/am335x-bone.dtb > arch/arm/boot/zImage-dtb.am335x-bone
$ scripts/mkuboot.sh -A arm -O linux -C none  -T kernel -a 0x80008000 -e 0x80008000 -n 'Linux' -d arch/arm/boot/zImage-dtb.am335x-bone arch/arm/boot/uImage-dtb.am335x-bone

Appended DTBs work fine on the testbed here.
