Sv32 is what every 32-bit RISC-V CPU with an MMU uses. It is a full MMU. You can run Linux on it.
Sure, but what the S31 calls "MMU" is not an Sv32 MMU; therefore my comment.
The documentation states:
> Compliant with RISC-V Sv32 virtual memory scheme

Ok, I see. The S3’s "MMU" is just an external-memory mapper, not a virtual-memory MMU. The S31 apparently has both, that mapper plus an architectural CPU-side Sv32 MMU; that offers indeed a lot of interesting possibilities.
