define Package/bcm4908img/description
  CFE bootloader for BCM4908 uses custom image format. It consists of:

  2. bootfs JFFS2 partition (cferam, kernel, DTB and optional helper files)
  3. padding
  4. rootfs simply appended to the bootfs + padding
  5. tail with checksum and basic device info

  This util allows creating, modifying and extracting from BCM4908 images.
