 Using this, you can change the bitstream firmware on bitforce singles.
 It is untested with other devices. Use at your own risk!

+To flash your BFL, specify the BFL port and the flash file e.g.:
- ./bitforce-firmware-flash /dev/ttyUSB0 alphaminer_832.bfl
+ sudo ./bitforce-firmware-flash /dev/ttyUSB0 alphaminer_832.bfl
 It takes a bit under 3 minutes to flash a BFL and shows a progress % counter
+Once it completes, you may also need to wait about 15 seconds,
+then power the BFL off and on again

+If you get an error at the end of the BFL flash process stating:
+ "Error reading response from ZBX"
+it may have worked successfully anyway.
+Test mining on it to be sure if it worked or not.

+You need to give cgminer about 10 minutes mining with the BFL to be sure of
+the MH/s value reported with the changed firmware - and the MH/s reported
+will be less than the firmware speed since you lose work on every block change.
