description:
Add support for bcm 43xx devices using the btuart h5 protocol.
Currently It will only load 1 firmware image for rpi3.
To use change to the directory containing the firmware BCM4340A1.hcd.
Then issue: btattach -FPi 115200 bcm43xx /dev/ttydevice 921600.
Then you can use the bluetooth device btfive0.
This enables the embedded bluetooth controller on rpi3.
