SPECS FOR TEH FIASCO FIRMWARE FILE FORMAT ffff!
-----------------------------------------------

  These notes has not been taken properly and may be wrong. It must
  be revised to fit the reality. But this is mostly a general idea:


FILE HEADER

   1 byte = 0xb4    --  signature
   4 bytes          --  firmware name length (big endian)
   6 bytes          --  versioning info ( byte 4 is format version )
   N-6 bytes        --  firmware name (zero fill)


PIECE HEADER

   1 byte = 0x54    --  piece signature
   6 bytes          --  unknown
   2 bytes          --  checksum for the piece contents (xorpair)
  12 bytes          --  piece name (first byte is FF if is the last)
   4 bytes          --  piece size (big endian)
   4 bytes          --  unknown
             block {
   1 byte           --  if (value '1'-'9') { ..there's a comment.. }
   1 byte           --  length of comment
   N bytes          --  comment
             }
   N bytes          -- piece data
