Routine Description:

  Retrieves a Unicode string that is the user readable name of the EFI Driver.

Arguments:

  This       - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
  Language   - A pointer to a three character ISO 639-2 language identifier.
               This is the language of the driver name that that the caller 
               is requesting, and it must match one of the languages 
               specified in SupportedLanguages.  The number of languages
               supported by a driver is up to the driver writer.
  DriverName - A pointer to the Unicode string to return.  This Unicode
               string is the name of the driver specified by This in the
               language specified by Language.

Returns:

  EFI_SUCCES            - The Unicode string for the Driver specified by
                          This and the language specified by Language was
                          returned in DriverName.
  EFI_INVALID_PARAMETER - Language is NULL.
  EFI_INVALID_PARAMETER - DriverName is NULL.
  EFI_UNSUPPORTED       - The driver specified by This does not support the 
                          language specified by Language.

Routine Description:

  Retrieves a Unicode string that is the user readable name of the controller
  that is being managed by an EFI Driver.

Arguments:

  This             - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
  ControllerHandle - The handle of a controller that the driver specified by 
                     This is managing.  This handle specifies the controller 
                     whose name is to be returned.
  ChildHandle      - The handle of the child controller to retrieve the name 
                     of.  This is an optional parameter that may be NULL.
                     It will be NULL for device drivers.  It will also be
                     NULL for a bus drivers that wish to retrieve the name of
                     the bus controller.  It will not be NULL for a bus
                     driver that wishes to retrieve the name of a child
                     controller.
  Language         - A pointer to a three character ISO 639-2 language 
                     identifier.  This is the language of the controller
                     name that that the caller is requesting, and it must
                     match one of the languages specified in supported
                     languages. The number of languages supported by a driver
                     is up to the driver writer.
  ControllerName   - A pointer to the Unicode string to return.  This Unicode
                     string is the name of the controller specified by 
                     ControllerHandle and ChildHandle in the language
                     specified by Language from the point of view of the
                     driver specified by This.

Returns:

  EFI_SUCCESS           - The Unicode string for the user readable name in
                          the language specified by Language for the driver
                          specified by This was returned in DriverName.
  EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
  EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid
                          EFI_HANDLE.
  EFI_INVALID_PARAMETER - Language is NULL.
  EFI_INVALID_PARAMETER - ControllerName is NULL.
  EFI_UNSUPPORTED       - The driver specified by This is not currently
                          managing the controller specified by
                          ControllerHandle and ChildHandle.
  EFI_UNSUPPORTED       - The driver specified by This does not support the 
                          language specified by Language.
