    Currently, usr/gen_initramfs.sh takes care of all the use-cases:
    
     [1] generates a cpio file unless CONFIG_INITRAMFS_SOURCE points to
         a single cpio archive
    
     [2] If CONFIG_INITRAMFS_SOURCE is the path to a cpio archive,
         use it as-is.
    
     [3] Compress the cpio file according to CONFIG_INITRAMFS_COMPRESSION_*
         unless it is passed a compressed archive.
    
    To simplify the script, move [2] and [3] to usr/Makefile.
    
    If CONFIG_INITRAMFS_SOURCE is the path to a cpio archive, there is
    no need to run this shell script.
    
    For the cpio archive compression, you can re-use the rules from
    scripts/Makefile.lib .
