Function indicates the current completion progress of a firmware update.
Platform may override with its own specific function.
@param[in] Completion A value between 0 and 100 indicating the current
completion progress of a firmware update. This
value must the the same or higher than previous
calls to this service. The first call of 0 or a
value of 0 after reaching a value of 100 resets
the progress indicator to 0.
@param[in] Color Color of the progress indicator. Only used when
Completion is 0 to set the color of the progress
indicator. If Color is NULL, then the default color
is used.
@retval EFI_SUCCESS Progress displayed successfully.
@retval EFI_INVALID_PARAMETER Completion is not in range 0..100.
@retval EFI_INVALID_PARAMETER Completion is less than Completion value from
a previous call to this service.
@retval EFI_NOT_READY The device used to indicate progress is not
available.
