BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4654 An SVSM requires a calling area page whose address (CAA) is used by the SVSM to communicate and process the SVSM request. Add a pre-defined page area to the OvmfPkg and AmdSev packages and define corresponding PCDs used to communicate the location and size of the area. Keep the AmdSev package in sync with the OvmfPkg and adjust the AmdSev launch and hash area memory locations.
