/*

* The purpose of this code is to signal the operational status of a
|
|
* target which usually boots over the network; while running in
|
|
* U-Boot, 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.
