Routine Description: 

  Provides an interface that a software module can call to report an ASF DXE status code.

Arguments:

  PeiServices - PeiServices pointer.

  Type     - Indicates the type of status code being reported.
  
  Value    - Describes the current status of a hardware or software entity.
             This included information about the class and subclass that is 
             used to classify the entity as well as an operation.
  
  Instance - The enumeration of a hardware or software entity within 
             the system. Valid instance numbers start with 1.
  
  CallerId - This optional parameter may be used to identify the caller.
             This parameter allows the status code driver to apply different 
             rules to different callers.
  
  Data     - This optional parameter may be used to pass additional data.

Returns: 
  
  None
