    Special content staging hook called before do_prepare_partition(),
    normally empty.
    Typically, a partition will just use the passed-in parame e.g
    straight bootimg_dir, etc, but in some cases, things need to
    be more tailored e.g. to use a deploy dir + /boot, etc.  This
    hook allows those files to be staged in a customized fashion.
    Not that get_bitbake_var() allows you to acces non-standard
    variables that you might want to use for this.
