Ard, Leif,
I am a bit interested in how ARM platform supports the MP?
PI Spec defines below protocol but I failed to find a driver in ARM platform 
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
