> From the previous discussions, I got the impression that other than the 'novel' way they're integrated, the actual SMMU implementations were unmodified Arm MMU-500s. Is that the case, or have I misread something?

The ARM MMU-500 implementation is unmodified.  It is the way the are integrated and used together(for interleaved accesses) is different from regular ARM MMU-500.
I have added it to get the model number and to be able differentiate the SMMU implementation in arm-smmu-impl.c.
