On the Yocto image there is a single partition and the kernel and dtb are present in the 'boot' directory. Change it accordingly so that the board can boot the Yocto image by default. Use the generic 'load' command instead, which is able to read from an ext4 partition. Signed-off-by: Fabio Estevam <festevam@denx.de>
