REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2726 When FSP switching stack and calling bootloader functions, the function parameter in stack may not be accessible easily. We can store the function parameter pointer to FspGlobalData and retrieve it after stack switched. Also need to add Loader2PeiSwitchStack () to header file as public function for platform FSP code to consume.
