How does uboot set ethaddr when the correct fuses have a valid MAC address?

I'm working on the processor IMX8DQXPRM. I have programmed the MAC Address to the fuses. When i boot the system, uboot complains that MAC Address is not set therefore, using a random address.


Is it right in understanding that the ethaddr variable of Uboot conveys the MAC address to Linux kernel?


Is there some kind of a CONFIG flag that needs to be set so that the Uboot's ethaddr variable reads the address from the fuses?


Is there some change in device tree to be made?
