+ Report status code to OEM device.\r
+ \r
+ @param CodeType Indicates the type of status code being reported. Type EFI_STATUS_CODE_TYPE is defined in "Related Definitions" below.\r
+ \r
+ @param Value Describes the current status of a hardware or software entity. \r
+ This included information about the class and subclass that is used to classify the entity \r
+ as well as an operation. 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
+ Type EFI_STATUS_CODE_VALUE is defined in "Related Definitions" below. \r
+ Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.\r
+ \r
+ @param Instance The enumeration of a hardware or software entity within the system. \r
+ A system may contain multiple entities that match a class/subclass pairing. \r
+ The instance differentiates between them. An instance of 0 indicates that instance information is unavailable, \r
+ not meaningful, or not relevant. Valid instance numbers start with 1.\r
+\r
+\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 different callers. \r
+ Type EFI_GUID is defined in InstallProtocolInterface() in the EFI 1.10 Specification.\r
+\r
+\r
+ @param Data This optional parameter may be used to pass additional data\r
+ \r
+ @return The function always return EFI_SUCCESS.\r
