This patch series adds ethernet support for the StarFive JH7100 SoC and makes it available for the StarFive VisionFive V1 and BeagleV Starlight boards, although I could only validate on the former SBC. The work is heavily based on the reference implementation [1] and depends the non-coherent DMA support provided by Emil via the SiFive Composable Cache controller [2].
