Instead of embedding the initrd cpio archive into the kernel, allow for having an external ramdisk added to the FIT or uImage. This is useful to overcome kernel size limitations present in many stock bootloaders, as the ramdisk is then loaded seperately and doesn't add to the kernel size. Hence we can have larger ramdisks to host ie. installers with all binaries to flash included (or a web-based firmware selector). In terms of performance and total size the differences are neglectible. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
