As far as I'm aware, none of the HW platforms that have the mvneta IP as Ethernet MAC have an IOMMU/SMMU or similar. The more recent Marvell platforms are using the mvpp2 IP instead. > On that point, I'm wondering whether there's much value keeping > Thomas' maintainer's entries for Marvell stuff - any comment Thomas? Clearly, I am no longer actively working on Marvell platforms, and it would certainly be fine to see other people step up to maintain the mvneta driver and drop my entry.
