[PATCH 00/12] Enable networking support for StarFive JH7100 SoC

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.
