  57 # 1. It's simple tar file (GNU standard), but it must have ".firm" suffix.
  58 # 2. It contains two images: kernel and romdisk. Both are required.
  59 # 3. Every image has header and trailer file.
  60 # 4. The struct of tar firmware is: header kernel trailer header romdisk trailer
  61 # 5. In header file are some strings used to describe image. It was decoded from
  62 #    factory image.
  63 # 6. Version format in header file is restricted by Original FW.
  64 # 7. Trailer file contains MD5 sum string of header and image file.
  65 # 8. Firmware file must have <=24MB size.
