  @param  PeiServices      An indirect pointer to the EFI_PEI_SERVICES table published by the PEI Foundation.\r
  @param  CodeType         Indicates the type of status code being reported.\r
  @param  Value            Describes the current status of a hardware or\r
                           software entity. This includes information about the class and\r
                           subclass that is used to classify the entity as well as an operation.\r
                           For progress codes, the operation is the current activity.\r
                           For error codes, it is the exception.For debug codes,it is not defined at this time.\r
  @param  Instance         The enumeration of a hardware or software entity within\r
                           the system. A system may contain multiple entities that match a class/subclass\r
                           pairing. The instance differentiates between them. An instance of 0 indicates\r
                           that instance information is unavailable, not meaningful, or not relevant.\r
                           Valid instance numbers start with 1.\r
  @param  CallerId         This optional parameter may be used to identify the caller.\r
                           This parameter allows the status code driver to apply different rules to\r
                           different callers.\r
  @param  Data             This optional parameter may be used to pass additional data.\r
