Support for Ethernet on KC705

Hello, We are working on running CVA6(64bit) with the CVA6-SDK on the Xilinx KC705 evaluation board. What we did; 1)We generated the FPGA bitstream for CVA6 on the KC705 using the main CVA6 repository successfully 2)We built the Linux image through the CVA6-SDK and flashed it to the SD card. 3)The board boots correctly and UART terminal works normally.

the issue is Ethernet does not work on the KC705. The network interface appears in "ip link show" as eth0, but there is no connectivity, no IP address is assigned, and the Marvell PHY does not seem to initialize properly in the logs.

kernel logs says "no PHY found in range address 0..31" we found that phy address 0x7 on the kc705 board. we tried to edit mdio dts files with new phy address but no luck.

could you help me which parts of the CVA6-SDK need to be modified to enable Ethernet support for KC705? thanks in advance
