The following flash-related base addresses: - PcdFlashNvStorageVariableBase64, - PcdFlashNvStorageFtwWorkingBase, - PcdFlashNvStorageFtwSpareBase, are always set to constant (invariable) values in the "-D SMM_REQUIRE" build of OVMF. (That's because in the SMM build, actual pflash is a hard requirement, and the RAM-based emulation is never available.) Set said PCDs statically, at build. This will allow us to depend on their values in the PEI phase. When SMM_REQUIRE is FALSE, this change has no effect (confirmed by report file comparison). When SMM_REQUIRE is TRUE, the report file shows the following changes: - "PcdOvmfFlashNvStorageFtwSpareBase" and "PcdOvmfFlashNvStorageFtwWorkingBase" are no longer consumed by any module directly, - for "PcdFlashNvStorageFtwSpareBase", "PcdFlashNvStorageFtwWorkingBase" and "PcdFlashNvStorageVariableBase64", the access method changes from DYN to FIXED, - for the latter PCDs, the zero (dynamic default) values are replaced with the desired constants.
