+/*++
+
+Routine Description:
+
+  The WaitForTick() function waits for the number of ticks specified by
+  TickNumber from a known time source in the platform.  If TickNumber of
+  ticks are detected, then EFI_SUCCESS is returned.  The actual time passed
+  between entry of this function and the first tick is between 0 and
+  TickPeriod 100 nS units.  If you want to guarantee that at least TickPeriod
+  time has elapsed, wait for two ticks.  This function waits for a hardware
+  event to determine when a tick occurs.  It is possible for interrupt
+  processing, or exception processing to interrupt the execution of the
+  WaitForTick() function.  Depending on the hardware source for the ticks, it
+  is possible for a tick to be missed.  This function cannot guarantee that
+  ticks will not be missed.  If a timeout occurs waiting for the specified
+  number of ticks, then EFI_TIMEOUT is returned.
+
+Arguments:
+
+  This       - The EFI_METRONOME_ARCH_PROTOCOL instance.
+  TickNumber - Number of ticks to wait.
+
+Returns:
+
+  EFI_SUCCESS - The wait for the number of ticks specified by TickNumber
+                succeeded.
