Missing step: build the device tree blob.

The "bootm" command without arguments does just start the Linux kernel
image. In this form, it does NOT pass the device tree to the Linux
kernel. You must use

	=> bootm 01000000 - <dtb_addr>

instead (after downloading the DTB to the <dtb_addr> address).

Best regards,
