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 1*: As of next-20231214, dependencies [2] & [3] have been merged. *Update 2*: Since v5, the dwmac patches will be handled via [4], while the clock patches subset via [5].
