1/** @file 2Module produce Framework's EFI_PEI_FV_FILE_LOADER_PPI top of EFI_PEI_LOAD_FILE_PPI. 3 4UEFI PI Spec supersedes Intel's Framework Specs. 5EFI_PEI_FV_FILE_LOADER_PPI defined in Intel Framework Pkg is replaced by EFI_PEI_LOAD_FILE_PPI 6in MdePkg. 7This module produces EFI_PEI_FV_FILE_LOADER_PPI on top of EFI_PEI_LOAD_FILE_PPI . 8This module is used on platform when both of these two conditions are true: 91) Framework module consumes EFI_PEI_FV_FILE_LOADER_PPI is present. 102) The platform has PI modules that produce EFI_PEI_LOAD_FILE_PPI. 11 12Copyright (c) 2008 - 2010, Intel Corporation.
