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