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.
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.
To achieve this the current CPU code is moved to its own mips32 subdirectory. All Mips32 boards have to use mips32 as config switch in board.cfg.
