  69 # 3. Every image has header and trailer file.
  70 # 4. The struct of tar firmware is: header kernel trailer header romdisk trailer
  71 # 5. In header file are some strings used to describe image. It was decoded from
  72 #    factory image.
  73 # 6. Version format in header file is restricted by Original FW.
  74 # 7. Trailer file contains MD5 sum string of header and image file.
  75 # 8. Firmware file must have <=24MB size.
