+Module produce Framework's EFI_PEI_FV_FILE_LOADER_PPI top of EFI_PEI_LOAD_FILE_PPI.
+
+UEFI PI Spec supersedes Intel's Framework Specs.
+EFI_PEI_FV_FILE_LOADER_PPI defined in Intel Framework Pkg is replaced by EFI_PEI_LOAD_FILE_PPI
+in MdePkg.
+This module produces EFI_PEI_FV_FILE_LOADER_PPI on top of EFI_PEI_LOAD_FILE_PPI .
+This module is used on platform when both of these two conditions are true:
+1) Framework module consumes EFI_PEI_FV_FILE_LOADER_PPI is present.
+2) The platform has PI modules that produce EFI_PEI_LOAD_FILE_PPI.
