/**
  This service executes a caller provided function on all enabled APs.

  @param[in]  Procedure               A pointer to the function to be run on
                                      enabled APs of the system. See type
                                      EFI_AP_PROCEDURE.
  @param[in]  SingleThread            If TRUE, then all the enabled APs execute
                                      the function specified by Procedure one by
                                      one, in ascending order of processor handle
                                      number.  If FALSE, then all the enabled APs
                                      execute the function specified by Procedure
                                      simultaneously.
  @param[in]  WaitEvent               The event created by the caller with CreateEvent()
                                      service.  If it is NULL, then execute in
                                      blocking mode. BSP waits until all APs finish
                                      or TimeoutInMicroSeconds expires.  If it's
                                      not NULL, then execute in non-blocking mode.
                                      BSP requests the function specified by
                                      Procedure to be started on all the enabled
                                      APs, and go on executing immediately. If
                                      all return from Procedure, or TimeoutInMicroSeconds
                                      expires, this event is signaled. The BSP
                                      can use the CheckEvent() or WaitForEvent()
                                      services to check the state of event.  Type
                                      EFI_EVENT is defined in CreateEvent() in
                                      the Unified Extensible Firmware Interface
                                      Specification.
  @param[in]  TimeoutInMicroseconds   Indicates the time limit in microseconds for
                                      APs to return from Procedure, either for
                                      blocking or non-blocking mode. Zero means
                                      infinity.  If the timeout expires before
                                      all APs return from Procedure, then Procedure
                                      on the failed APs is terminated. All enabled
                                      APs are available for next function assigned
                                      by MpInitLibStartupAllAPs() or

                                      If the timeout expires in blocking mode,
                                      BSP returns EFI_TIMEOUT.  If the timeout
                                      expires in non-blocking mode, WaitEvent
                                      is signaled with SignalEvent().
  @param[in]  ProcedureArgument       The parameter passed into Procedure for
                                      all APs.
  @param[out] FailedCpuList           If NULL, this parameter is ignored. Otherwise,
                                      if all APs finish successfully, then its
                                      content is set to NULL. If not all APs
                                      finish before timeout expires, then its
                                      content is set to address of the buffer
                                      holding handle numbers of the failed APs.
                                      The buffer is allocated by MP Initialization
                                      library, and it's the caller's responsibility to
                                      free the buffer with FreePool() service.
                                      In blocking mode, it is ready for consumption
                                      when the call returns. In non-blocking mode,
                                      it is ready when WaitEvent is signaled.  The
                                      list of failed CPU is terminated by
                                      END_OF_CPU_LIST.

  @retval EFI_SUCCESS             In blocking mode, all APs have finished before
                                  the timeout expired.

  @param[in]  WaitEvent               The event created by the caller with CreateEvent()
                                      service.  If it is NULL, then execute in
                                      blocking mode. BSP waits until this AP finish
                                      or TimeoutInMicroSeconds expires.  If it's
                                      not NULL, then execute in non-blocking mode.
                                      BSP requests the function specified by
                                      Procedure to be started on this AP,
                                      and go on executing immediately. If this AP
                                      return from Procedure or TimeoutInMicroSeconds
                                      expires, this event is signaled. The BSP
                                      can use the CheckEvent() or WaitForEvent()
                                      services to check the state of event.  Type
                                      EFI_EVENT is defined in CreateEvent() in
                                      the Unified Extensible Firmware Interface
                                      Specification.
  @param[in]  TimeoutInMicroseconds   Indicates the time limit in microseconds for
                                      this AP to finish this Procedure, either for
                                      blocking or non-blocking mode. Zero means
                                      infinity.  If the timeout expires before
                                      this AP returns from Procedure, then Procedure
                                      on the AP is terminated. The
                                      AP is available for next function assigned
                                      by MpInitLibStartupAllAPs() or
                                      MpInitLibStartupThisAP().
                                      If the timeout expires in blocking mode,
                                      BSP returns EFI_TIMEOUT.  If the timeout
                                      expires in non-blocking mode, WaitEvent
                                      is signaled with SignalEvent().
  @param[in]  ProcedureArgument       The parameter passed into Procedure on the
                                      specified AP.
  @param[out] Finished                If NULL, this parameter is ignored.  In
                                      blocking mode, this parameter is ignored.
                                      In non-blocking mode, if AP returns from
                                      Procedure before the timeout expires, its
                                      content is set to TRUE. Otherwise, the
                                      value is set to FALSE. The caller can
                                      determine if the AP returned from Procedure
                                      by evaluating this value.

  @retval EFI_SUCCESS             In blocking mode, specified AP finished before
                                  the timeout expires.
  @retval EFI_SUCCESS             In non-blocking mode, the function has been
                                  dispatched to specified AP.
  @retval EFI_UNSUPPORTED         A non-blocking mode request was made after the
                                  UEFI event EFI_EVENT_GROUP_READY_TO_BOOT was
                                  signaled.
  @retval EFI_UNSUPPORTED         WaitEvent is not NULL if non-blocking mode is not
                                  supported.

  @retval EFI_TIMEOUT             In blocking mode, the timeout expired before
                                  the specified AP has finished.
