This adds a driver for the LiteX network device, LiteEth. v4 Fixes the bindings and adds r-b tags from Gabriel and Rob. v3 Updates the bindings to describe the slots in a way that makes more sense for the hardware, instead of trying to fit some existing properties. The driver is updated to use these bindings, and fix some issues pointed out by Gabriel. v2 Addresses feedback from Jakub, with detailed changes in each patch. It also moves to the litex register accessors so the system works on big endian litex platforms. I tested with mor1k on an Arty A7-100T. I have removed the mdio aspects of the driver as they are not needed for basic operation. I will continue to work on adding support in the future, but I don't think it needs to block the mac driver going in. The binding describes the mdio registers, and has been fixed to not show any warnings against dtschema master. LiteEth is a simple driver for the FPGA based Ethernet device used in various RISC-V, PowerPC's microwatt, OpenRISC's mor1k and other FPGA based systems on chip.
