+ Report status code to OEM device.
+
+ @param CodeType Indicates the type of status code being reported. Type EFI_STATUS_CODE_TYPE is defined in "Related Definitionsˇ± below.
+
+ @param 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. For progress codes, the operation is the current activity.
+ For error codes, it is the exception. For debug codes, it is not defined at this time.
+ Type EFI_STATUS_CODE_VALUE is defined in ˇ°Related Definitionsˇ± below.
+ Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.
+
+ @param Instance The enumeration of a hardware or software entity within the system.
+ A system may contain multiple entities that match a class/subclass pairing.
+ The instance differentiates between them. An instance of 0 indicates that instance information is unavailable,
+ not meaningful, or not relevant. Valid instance numbers start with 1.
+
+
+ @param 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.
+ Type EFI_GUID is defined in InstallProtocolInterface() in the EFI 1.10 Specification.
+
+
+ @param Data This optional parameter may be used to pass additional data
+
+ @return The function always return EFI_SUCCESS.
