| 14 | | This is a {{{cpio.gz}}} that you pass to the kernel when booting. If doing this with U-Boot its the 2nd (middle) arg to bootm/booti/bootz. Note that {{{bootm}}} expects a uImage and uramdisk which have U-Boot wrappers (created with the {{{mkimage}}} tool from the {{{u-boot-tools}}} package) around the images. |
| | 14 | This is a ramdisk image (cpio, or compressed cpio if you have enabled ramdisk compression in your kernel) that you pass to the kernel when booting. If doing this with U-Boot its the 2nd (middle) arg to bootm/booti/bootz. |

| | 16 | Note that {{{bootm}}} expects a uImage and uramdisk which have U-Boot wrappers (created with the {{{mkimage}}} tool from the {{{u-boot-tools}}} package) around the images. U-Boot must have CONFIG_LEGACY_IMAGE_FORMAT enabled for this. Note that arm64 does not support compressed kernel Images so you must use booti for arm64 (or bootm with a FIT image). |

| | 18 | Note that {{{booti}}} requires passing the size of the ramdisk by specifying <rdaddr>:<filesize and U-Boot must have CONFIG_SUPPORT_RAW_INITRD enabled. You can also use a uramdisk with booti as long as you have CONFIG_LEGACY_IMAGE_FORMAT enabled. |
