Powerpc 601 is rather old powerpc which as some important limitations compared to other book3s/32 powerpcs: - No Timebase. - Common BATs for instruction and data. - No execution protection in segment registers. - No RI bit in MSR - ... It is starting to be difficult and cumbersome to maintain kernels that are compatible both with 601 and other 6xx cores. Create a compiletime option to exclusively select either powerpc 601 or other 6xx.
