REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2792 The BeepDebugFeaturePkg include some useful beep debug libraries, such as get beep value from status code and beep. It provide a library BeepStatusCodeHandlerLib used by edk2 StatusCodeHandler.efi, used to do beep if needed. It also provide a library of BeepMap lib, it map the status code to beep value. A library of Beep lib is needed by platform, and this pkg has a Null implementation.

/**

NULL implemented of Beep() function, just return directly.
|
|
Normal Beep() function will do the following:
|
|
|
|
Sends a 32-bit value to Beep device.
|
|
|
|
Sends the 32-bit value specified by Value to Beep device, and returns Value.
|
|
Some implementations of this library function may perform I/O operations
|
|
directly to Beep device. Other implementations may send Value to
|
|
ReportStatusCode(), and the status code reporting mechanism will eventually
|
|
display the 32-bit value on the status reporting device.
|
|
|
|
Beep() must actively prevent recursion. If Beep() is called while
|
|
processing another Post Code Library function, then
|
|
Beep() must return Value immediately.
|
|
|
|
@param Value Beep count.
