PS1: 
From the FSP code, Index one shouldn't work, right?

//
  // FSPS UPD has hard allocated configuration space for only 2 UFS controllers. Be sure to change this loop termination
  // condition after adding more space in FSPS UPD.
  //
  for (UfsIndex = 0; (UfsIndex < PchGetMaxUfsNum ()) && (UfsIndex < 2); UfsIndex++) {
    UfsConfig->UfsControllerConfig[UfsIndex].Enable = FspsUpd->FspsConfig.UfsEnable[UfsIndex];
  }
