* Structure is:
* 4 bytes: header: "OpFw".
* 4 bytes: GIT commit tag (short version of SHA1).
* 4 bytes: Unix timestamp of compile time.
* 2 bytes: target platform. Should follow same rule as BOARD_TYPE and BOARD_REVISION in board define files.
* 26 bytes: commit tag if it is there, otherwise branch name. '-dirty' may be added if needed. Zero-padded.
* ---- 40 bytes limit ---
* 20 bytes: SHA1 sum of the firmware.
* 40 bytes: free for now.
