commit 4cee01d8d428b9cea3a73fc3a4979898a3aaac00 Author: Oskar Enoksson enok@lysator.liu.se Date: Sun Feb 2 12:23:52 2014 +0100
Added powernow support for two new (old) AMD K8 CPU's
The added CPU's are OSA248CEP5AU and a OSP280 processors. The OSP280 VID/FID numbers have been found by experimentation and extrapolation/guesses from similar models. It has been verified to work fine under Linux (OpenSuse 12.2, kernel 3.4.63-2.44) with four different test-processors. Windows untested..
