Hi, Peter,

In ZYBO, there is an on-board eeprom that contains a unique MAC address for each board. In FSBL (before u-boot), the MAC address is read out from EEPROM and write to the corresponding registers in ETH controller. So, in u-boot env, mac-skip should be defined so that it will not over-write the unique MAC address.

So, I wonder if it should be done in dts file or there is other ways to do that.

It can be done in as follow up patch. U-Boot also supports SPL. It means if you want to read this address from EEPROM you should solve it just in u-boot. There should be some ways how to do it.

Thanks, Michal
