PI Spec defines below protocol but I failed to find a driver in ARM platfor= m producing this protocol. Or did I miss anything? typedef struct _EFI_MP_SERVICES_PROTOCOL { EFI_MP_SERVICES_GET_NUMBER_OF_PROCESSORS GetNumberOfProcessors; EFI_MP_SERVICES_GET_PROCESSOR_INFO GetProcessorInfo; EFI_MP_SERVICES_STARTUP_ALL_APS StartupAllAPs; EFI_MP_SERVICES_STARTUP_THIS_AP StartupThisAP; EFI_MP_SERVICES_SWITCH_BSP SwitchBSP; EFI_MP_SERVICES_ENABLEDISABLEAP EnableDisableAP; EFI_MP_SERVICES_WHOAMI WhoAmI; } EFI_MP_SERVICES_PROTOCOL; Thanks, Ray
