that was an assumption. I could not find any information about Purple. This patch series is a suggestion. Maybe there are better approaches like arch/mips/cpu/{mips4k|mips5k|mips24k|...|octeon}. > >> code resides in the global arch/mips/cpu directory.

My original intention was cleaning up the MIPS CPU directory as preparation to support new SoCs. I included this patch because Aaron asked for this separation some weeks ago but no one answered or commented ;) However I posted this series to get some feedback if such a change is wanted or acceptable. If so I prepare a new patch series. At least I hope the SoC separation is acceptable.
