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