-Module produce EFI_PEI_READ_ONLY_VARIABLE_PPI on top of EFI_PEI_READ_ONLY_VARIABLE2_PPI.
-UEFI PI Spec supersedes Intel's Framework Specs.
-# EFI_PEI_READ_ONLY_VARIABLE_PPI defined in Intel Framework Pkg is replaced by EFI_PEI_READ_ONLY_VARIABLE2_PPI
-# in MdePkg.
-# This module produces EFI_PEI_READ_ONLY_VARIABLE_PPI on top of EFI_PEI_READ_ONLY_VARIABLE2_PPI.
-# This module is used on platform when both of these two conditions are true:
-# 1) Framework module consumes EFI_PEI_READ_ONLY_VARIABLE_PPI is present.
-# 2) The platform has a PI module that only produces EFI_PEI_READ_ONLY_VARIABLE2_PPI.

-This module can't be used together with ReadOnlyVariable2ToReadOnlyVariableThunk module.
