Based on the surrounding rate KConfigs and the oscillator frequency, this patch marks it as valid for all OMAP1 platforms -- Richard, Tuukka, Tony, perhaps you can comment if this does not look right? In the long term, all of these CONFIG_OMAP_ARM_*MHZ should be removed. The OPP settings should be associated with the platform information in the structure data (perhaps by extending the omap_chip defines). The selection of which rates to use should be handled at runtime; rates that are impossible due to xtal frequency mismatch or SoC-type mismatch should not be included. If implemented correctly, this should save some CPU time and some memory on OMAP1 kernels.
