Hi Jörg,
According to recent errata, the IOMMU in R-Car Gen3 SoCs does not
support cache snoop transactions for page table walk requests.
Hence this patch series skips the related setup when running on R-Car
Gen3, after doing a customary cleanup of related definitions.
Tested on R-Car H3 ES2.0 with QEMU+KVM and VFIO for EtherAVB.
Thanks!
