Bug description:
Broadcom bluetooth chips require a tool called patchram uploader [1]
to load firmware. This applies to at least BCM20702 and BCM43142.
Although some of the devices have an OTPROM that contains required
firmware, but it is found that these devices would not have HFP/HSP
support unless a upgraded firmware is loaded via patchram uploader.
This tool requires hci device to do the firmware loading, but this may
cause some race condition between patchram tool and bluetoothd or
something that also works on hci interface.
Also it needs some hooks to make firmware loads after bootup, s3, s4,
rfkill, and device hotplug events. Implement this loader in kernel
module would make things more easier.
