-  TimerLib for ARM EB. Hardcoded to 100ns period
-
-  This library assume the following initialization, usually done in SEC. 
-
-  // configure SP810 to use 1MHz clock and disable
-  MmioAndThenOr32 (EB_SP810_CTRL_BASE + SP810_SYS_CTRL_REG, ~SP810_SYS_CTRL_TIMER2_EN, SP810_SYS_CTRL_TIMER2_TIMCLK);
-  // Enable
-  MmioOr32 (EB_SP810_CTRL_BASE + SP810_SYS_CTRL_REG, SP810_SYS_CTRL_TIMER2_EN);
-
-  // configure timer 2 for one shot operation, 32 bits, no prescaler, and interrupt disabled
-  MmioOr32 (EB_SP804_TIMER2_BASE + SP804_TIMER_CONTROL_REG, SP804_TIMER_CTRL_ONESHOT | SP804_TIMER_CTRL_32BIT | SP804_PRESCALE_DIV_1);
-
-  // preload the timer count register
-  MmioWrite32 (EB_SP804_TIMER2_BASE + SP804_TIMER_LOAD_REG, 1);
-
-  // enable the timer
-  MmioOr32 (EB_SP804_TIMER2_BASE + SP804_TIMER_CONTROL_REG, SP804_TIMER_CTRL_ENABLE);

-  Retrieves the 64-bit frequency in Hz and the range of performance counter

-  If StartValue is not NULL, then the value that the performance counter starts
-  with immediately after is it rolls over is returned in StartValue. If
-  EndValue is not NULL, then the value that the performance counter end with
-  immediately before it rolls over is returned in EndValue. The 64-bit
-  frequency of the performance counter in Hz is always returned. If StartValue
-  is less than EndValue, then the performance counter counts up. If StartValue
-  is greater than EndValue, then the performance counter counts down. For
-  example, a 64-bit free running counter that counts up would have a StartValue
