     28   Publishes an interface that allows PEIMs to report status codes.
     29 
     30   This function implements EFI_PEI_PROGRESS_CODE_PPI.ReportStatusCode().
     31   It publishes an interface that allows PEIMs to report status codes.
     32 
     33   @param  PeiServices      An indirect pointer to the EFI_PEI_SERVICES table published by the PEI Foundation.
     34   @param  CodeType         Indicates the type of status code being reported.
     35   @param  Value            Describes the current status of a hardware or
     36                            software entity. This includes information about the class and
     37                            subclass that is used to classify the entity as well as an operation.
     38                            For progress codes, the operation is the current activity.
     39                            For error codes, it is the exception.For debug codes,it is not defined at this time.
     40   @param  Instance         The enumeration of a hardware or software entity within
     41                            the system. A system may contain multiple entities that match a class/subclass
     42                            pairing. The instance differentiates between them. An instance of 0 indicates
     43                            that instance information is unavailable, not meaningful, or not relevant.
     44                            Valid instance numbers start with 1.
     45   @param  CallerId         This optional parameter may be used to identify the caller.
     46                            This parameter allows the status code driver to apply different rules to
     47                            different callers.
     48   @param  Data             This optional parameter may be used to pass additional data.
     49 
     50   @retval EFI_SUCCESS      The function completed successfully.
