It includes 4 drivers: 1. UfsPassThruDxe, which is a UEFI driver and consumes EFI_UFS_HOST_CONTROLLER_PROTOCOL and produces EFI_EXT_SCSI_PASS_THRU_PROTOCOL 2. UfsPciHcDxe, which is specific for pci-based UFS HC implementation and is a UEFI driver to produce EFI_UFS_HOST_CONTROLLER_PROTOCOL. 3. UfsBlockIoPei, which is a PEI driver and consumes EFI_UFS_HOST_CONTROLLER_PPI and produces EFI_PEI_VIRTUAL_BLOCK_IO_PPI. 4. UfsPciHcPei, which is specific for pci-based UFS HC implementation and is a PEI driver to produce EFI_UFS_HOST_CONTROLLER_PPI.
