I've been meaning to upstream pwm-beeper support for a piezobuzzer, but it would be a real shame if the obnoxious buzzing would delay the boot. So let me present asynchronous beeping support for barebox. If you don't have the suitable hardware lying around you can synth your own tunes on the barebox sandbox shell as well.
