I do compiled Openwrt only kernel with initramfs(CPIO).at output files ,i see some file:

openwrt-ar71xx-generic-nbg460n_550n_550nh-u-boot.bin
openwrt-ar71xx-generic-rootfs.cpio.gz
openwrt-ar71xx-generic-rootfs.tar.gz
openwrt-ar71xx-generic-uImage-initramfs-gzip.bin
openwrt-ar71xx-generic-uImage-initramfs-lzma.bin
openwrt-ar71xx-generic-vmlinux-initramfs.bin
openwrt-ar71xx-generic-vmlinux-initramfs.elf
openwrt-ar71xx-generic-vmlinux-initramfs.gz
openwrt-ar71xx-generic-vmlinux-initramfs.lzma

.Is  openwrt-ar71xx-generic-rootfs.cpio.gz  file  located in the kernel?
My mean is that for put kernel in the My nand,I need both of files:
(openwrt-ar71xx-generic-rootfs.cpio.gz    &   openwrt-ar71xx-generic-vmlinux-initramfs.bin)   or just (openwrt-ar71xx-generic-vmlinux-initramfs.bin) file?
Note: I think CPIO file placed as embedded in the Kernel at compile time. Is my thinking correct?
