@nicram for now:
should work. I'll look into a source for this firmware, but no promises (if it's not upstream in the kernel I'm less inclined to do Broadcoms job for them).
Edit: redistribution of the BCM20702A1 firmware doesn't appear to be an option - the binary firmware files you found have been created from files downloaded from the Windows Update site and are not officially licensed by Broadcom for use with Linux. So for now you'll just need to manually install the firmware using the instructions I've given above.
Code:
mkdir -p /storage/.config/firmware/brcm
cp /storage/downloads/BCM20702A1-0489-e046.hcd /storage/.config/firmware/brcm
reboot
