Closed source package '''bt-firmware'''

As name suggest, this is bluetooth firmware. (BCM2048 is the name of the Bluetooth chip from Broadcom.)

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 transmitting works. Radio is on the same chip, but it isn't using this firmware-file)

Alternatives:
