Hi Thomas & Dominik, Thanks a lot for your suggestions. I followed the steps ( also looked into the cpu-freq documentation inside the linux kernel tree) & included the flags related to the CPU frequency. After booting the kernel however I am not able to see the cpufreq folder inside /sys folder as you mentioned. I was expecting to see /cpufreq/scaling_setspeed, but the cpufreq folder is not present itself. I included all the frequency scaling options in the menuconfig option of the kernel. I rebulit the kernel and downloaded to the powerpc target. However the folder I mentioned is missing, I got a roadblock. I would be grateful if you have any recommendation for me, I would be able to move ahead from there.
