At least a smoke test here succeeded as well, I'm seeing replies to DHCP. However: | Model: StarFive VisionFive 2 v1.3B [...] | Net: | Warning: ethernet@16040000 (eth1) using random MAC address - e2:b9:39:bd:92:24 | | Warning: ethernet@16030000 (eth0) using random MAC address - 22:da:dc:e6:2c:17 | eth0: ethernet@16030000, eth1: ethernet@16040000 [...] What's missing to read the correct MACs from the EEPROM?

This series adds ethernet support for the StarFive JH7110 RISC-V SoC. The series includes PHY and MAC drivers. The PHY model is YT8531 (from Motorcomm Inc), and the MAC version is dwmac-5.20 (from Synopsys DesignWare). The implementation of the phy driver is ported from linux, but it has been adjusted for the u-boot framework. The PHY and MAC driver has been tested on the StarFive VisionFive 2 1.2A and 1.3B boards and works normally. For more information and support,you can visit RVspace wiki[1]. This patchset should be applied after the patchset [2].
