When loading the firmware, complete each chunk by sending an I2C flush command to the frontend. Some devices like the tm6000 seem to require this to properly flush the I2C buffers. The current code in tm6000 executes the flush command once after each I2C transfer, which slows down the firmware loading especially when loading large BASE type images.
