config CPU_FREQ_CBE tristate "CBE frequency scaling" depends on CBE_RAS && PPC_CELL default m help This adds the cpufreq driver for Cell BE processors. For details, take a look at <file:Documentation/cpu-freq/>. If you don't have such processor, say N config CPU_FREQ_CBE_PMI bool "CBE frequency scaling using PMI interface" depends on CPU_FREQ_CBE default n help 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. config CPU_FREQ_MAPLE bool "Support for Maple 970FX Evaluation Board" depends on PPC_MAPLE select CPU_FREQ_TABLE help This adds support for frequency switching on Maple 970FX Evaluation Board and compatible boards (IBM JS2x blades).
