Please implement MeasureFspFirmwareBlobWithCfg() directly here.
MeasureFspFirmwareBlobWithCfg () should be an internal function.
MeasureFspFirmwareBlob() may call MeasureFspFirmwareBlobWithCfg() based upon PCD.
MeasureFirmwareBlobWithCfg() should not be used because it should not exist.
Thank you
Yao Jiewen
