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}.

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.

Cheers,
Daniel
