9  * The purpose of this code is to signal the operational status of a
10  * target which usually boots over the network; while running in
11  * PCBoot, a status LED is blinking. As soon as a valid BOOTP reply
12  * message has been received, the LED is turned off. The Linux
13  * kernel, once it is running, will start blinking the LED again,
14  * with another frequency.
