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 requires the non-coherent DMA support provided by Emil via the Sifive Composable Cache controller. Also note there is an overlap in "[PATCH 08/12] net: stmmac: Add glue layer for StarFive JH7100 SoC" with the Yanhong Wang's upstreaming attempt [2]: "[PATCH v4 5/7] net: stmmac: Add glue layer for StarFive JH7110 SoCs". Since I cannot test the JH7110 SoC, I dropped the support for it from Emil's variant of the stmmac glue layer. Hence, we might need a bit of coordination in order to get this properly merged.
