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.
