My preference for this would go to: "microchip,mpfs-icicle-kit". This is the name used to order the board and what is written on the box. As a rule please use "mpfs" as identifier in place of "polarfire-soc", "pfsoc", "pse", "g5soc" or whatever other variation on the theme when not using the marketing name of the device. Regards, Cyril.

> > On the Icicle-Kit board, there are 2 etherents ports. Is there a > reason why this etherent port is disabled? > > Yes, the Icicle kit has two ethernet ports but only one MDIO interface between MAC and PHY-dual port is available i.e connected with ethernet 1 and other port(ethernet 0) MDIO interface is not connected with PHY in the FPGA design that's why it is disabled. only one ethernet port is enabled in the fpga design for Linux bring-up on the Icicle kit at present. We will update our FPGA design in the future to enable both ethernet ports.
