Subject: [PATCH 00/12] Enable networking support for StarFive JH7100 SoC
Date:   Sat, 11 Feb 2023 05:18:09 +0200

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.
