To add to this, we had a discussion at the RISC-V MC at plumbers last year (I think it was) about removing the K210 RISC-V SoC and associated RISC-V NOMMU support. But several people complained about that because several FPGAs implementing RISC-V cores are NOMMU (for obvious reasons for the FPGA case). So NOMMU is being used out there. -- Damien Le Moal Western Digital Research
