+         This enables support for a beeper that uses the i8254 timer chip.
+         This can emit beeps at a fixed frequency. It is possible to control
+         the length of the beeps, by turning a beep on, waiting for a period
+         of time, then turning it off.

+         Most Intel chips have an HDA (High-definition audio) codec which can
+         be used by U-Boot to play simple beeps. This is also sometimes called
+         Azalia which was the development code-name. It requires setup
