31 * The broadcom firmware assumes the rootfs starts the image,
32 * therefore uses the rootfs start (flash_image_address)
33 * to determine where to flash the image. Since we have the kernel first
34 * we have to give it the kernel address, but the crc uses the length
35 * associated with this address (root_length), which is added to the kernel
36 * length (kernel_length) to determine the length of image to flash and thus
37 * needs to be rootfs + deadcode (jffs2 EOF marker)
