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. Thank you Emil and Geert for helping with tests on BeagleV! The work is heavily based on the reference implementation [1] and depends on the SiFive Composable Cache controller and non-coherent DMA support provided by Emil via [2] and [3]. *Update*: as of next-20231214, all dependencies have been merged.
