   Original MIPS yes.  IIUC Chinese bought rights to use MIPS architecture   
   and that goes on.

   There are several 32-bit MCU-s and they probably have nontrival   
   part of the market.  There are also 64-bit processors, ATM   
   cheapest 64-bit Linux capable SBC-s known to me are RISC-V   
   (but ARM-based ones are quite close).  My impression is that   
   corresponding chips are used in security cameras (they have   
   special-purpose coprecessor for image recognition).   
   Several new chips offer choice of RISC-V or ARM, I am not sure   
   what percentage of users run them as ARM.   
      
   Currently big questions are:   
   - will Chinese dominate CPU market?   
   - which architectures will be used by Chinese?   
      
   It seems that main Chinese bet is on RISC-V.  They manufacture   
   a lot of ARM-s, but are not entirely comfortable with it.   
   There have few architectures that seem to still get some   
   developement.
