package I call bt-cal which is a replacement for bluetooth-sysinfo as a way to read the bluetooth MAC address from CAL and send it to the bluetooth driver. [...] The ultimate aim is that someone will modify this and make it talk to something more standard than the /sys/devices/platform/hci_h4p/hwaddr that it talks to now (allowing the non-standard interface to be removed from kernel-power/kernel-cssu/whatever).
