Julien,

Well, the thing I would generalize is an understanding that real chips
(automotive IVI, mobile) have no or has limited SMMU functionality.

For a limited SMMU functionality I would name Renesas RCAR H2 chip -
it has its own IPMMU instead of SMMU. It is claimed that IPMMU
implemets VMSAv7. But no VMSAv7 VE are supported by that IPMMU in
fact.

The most outstanding example is a chip with Cortex A15 MPCore, but
without any VE support at all.
