| 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) | |
