Closed source package bt-firmware

As name suggest, this is bluetooth firmware. BCM2048 is the name of the Bluetooth chip from Broadcom. Chip is combo chip and it contains bluetooth, and FM-radio receiver (FM-radio transmitter is in another chip: Silicon Labs Si4713 chipset).


Default installed version: 

bt-firmware:  Installed: 0.21-rc3+0m5

Provides files: 

/lib/firmware/bcmfw.bin

No package depends on it.

If removed (not suggested) 

*Not critical: device will still start
*Can't turn bluetooth ON (as expected).
*'About'-box will not show bluetooth address (cat /sys/devices/platform/hci_h4p/bdaddr is still showing it).
*FM-radio receiving stop working (error message: 'cannot activate chip')
(*FM-radio transmitting works as it is not in this chip)
