This adds the cpufreq driver for Cell BE processors.
For details, take a look at <file:Documentation/cpu-freq/>.

Select this, if you want to use the PMI interface
to switch frequencies. Using PMI, the
processor will not only be able to run at lower speed,
but also at lower core voltage.

PMI (Platform Management Interrupt) is a way to
communicate with the BMC (Baseboard Management Controller).
