Linux/Xtensa Kernel Configuration

└─>Auto calibration of the CPU clock rate
In linux kernel since version 2.6.13 (release Date: 2005-08-28)  
On some platforms (XT2000, for example), the CPU clock rate can
vary. The frequency can be determined, however, by measuring
against a well known, fixed frequency, such as an UART oscillator.
