+This way the build system will automatically override the respective PCDs. Off course these PCDs `gEfiMyTokenSpaceGuid.PcdFlashRegionBaseAddress` and `gEfiMyTokenSpaceGuid.PcdFlashRegionSize` must be defined in the DEC file. The first `<Offset>` PCD would be overriden with a respect to `FD.<...>].BaseAddress` value, i.e. it would be assigned to the `([FD.<...>].BaseAddress + <Offset>)` value.
