	  If you use the cpio archive as an initial RAM filesystem, make
	  sure the kernel contains the decompression algorithm selected
	  here.

	  Add a U-Boot header to the cpio root filesystem. This allows
	  the initramfs to be loaded with the bootm command in U-Boot.

	  The U-Boot image will be called rootfs.cpio.uboot
