From: Dengke Du <[email protected]> The program sensors-detect in lmsensors can't read the cpu information on ppc and arm arch, such as: fsl-t4xxx based on ppc.
This is because the program sensors-detect design for the x86 and x86-64, but weak on ppc and arm. So add the support for the ppc and arm, just add the correspond field to read in sensors-detect.
