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