/** @file
  Status code Runtime Protocol as defined in PI Specification VOLUME 2 DXE

  The StatusCode () service is added to the EFI system table and the 
  EFI_STATUS_CODE_ARCH_PROTOCOL_GUID protocol is registered with a NULL 
  pointer.

  No CRC of the EFI system table is required, since that is done in the DXE core.

  This code abstracts Status Code reporting.

/**
  Provides an interface that a software module can call to report a status code.

  @param  Type             Indicates the type of status code being reported.
  @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.
  @param  Instance         The enumeration of a hardware or software entity within
                           the system. 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.
  @param  Data             This optional parameter may be used to pass additional data.

  @retval EFI_SUCCESS           The function completed successfully
  @retval EFI_DEVICE_ERROR      The function should not be completed due to a device error.
