-config TSC_CALIBRATION_BYPASS
- bool "Bypass Time-Stamp Counter (TSC) calibration"
- default n
- help
- By default U-Boot automatically calibrates Time-Stamp Counter (TSC)
- running frequency via Model-Specific Register (MSR) and Programmable
- Interval Timer (PIT). If the calibration does not work on your board,
- select this option and provide a hardcoded TSC running frequency with
- CONFIG_TSC_FREQ_IN_MHZ below.
-
- Normally this option should be turned on in a simulation environment
- like qemu.

-config TSC_FREQ_IN_MHZ
