Scripts for generating boot-to-ramdisk images are now available. These can be used for example to boot from PXE or from a USB stick, as the ramdisk are self-contained and do not rely on any block devices after being loaded into RAM. The image generation framework has also been slightly cleaned up in order to better accomodate tarball sets bundling in images. Change-Id: I65a176832bd0d6954b430fa8305f90af0bd606c1
