 1.6  07-Feb-2023  mlelstv - Reconfigure port speed only when initial speed was different.
- Time out HCI commands instead of hanging forever.
- When bcm43xx reset fails, assume that firmware is already
running and start line discipline.

This allows to re-attach bcm43xx without reboot.
 1.5  03-Sep-2017  nat Fix copyright error.

Ok plunky@.
 1.4  14-Aug-2017  nat Set controller clock based on baud rate.
 1.3  10-Aug-2017  jmcneill Derive the firmware name from the device's local name instead of
hard-coding BCM4340A1. Search hw.firmware.path for the firmware image
instead of loading it from the current directory.
 1.2  10-Aug-2017  jakllsch remove currently-unused variables that trip up the build
 1.1  10-Aug-2017  nat 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.
