Is that true? What about purple SoC? IIUC It's based on MIPS 5Kc and capable of 64-bit, which MIPS32 is 32-bit only architecture.
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. This is not suitable if other Mips architectures like Mips64 or Octeon should be supported in the future.
Just for the record.
Personally, Octeon is sort of a special case. It's based on MIPS64 architecture, and definitely a MIPS SoC, but not usual MIPS machine. As Aaron already mentioned before, we have very few files sharable with other MIPS machines even in the Linux kernel case. I think it will take long time the Octeon port gets merged to upstream, regard- less of my opinions, because they have a lot of things need to be resolved prior to Octeon itself.
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
