How to configure UPHY8 to PCIe x1

Hi, vidyas.

The interface of the C4 controller has been designed on the custom carrier board, the Tx/Rx ,PERST#,CLKREQ# & REFCLK is fine. How to enable the PCIe C4 controller node in the software? Now, only uphy7 can recognize i210, and uphy8 can’t recognize i210 network card.

Thanks.
