Hm, I thought about replying to this thread writing something like "I'd like to co-operate by implementing CPU_FREQ on G2 / MPC824x", but then, looking at datasheets, it looks like it doesn't support any frequency scaling:-( So, out of luck here... Or have I overseen anything? Thanks Guennadi --- Guennadi Liakhovetski
