Looks like it might be hard for the board manufacturing? I mean each
board item need to have updated dtb file with base mac address, instead
to have common dtb for the board type.

And it sounds that platform data might be the way in case if the vendor
will implement platform device driver which will handle reading base mac
from eeprom (or other storage) depending on the board and put it to the
platform data which will be provided to prestera driver ?

Hi Vadym

This is not a new problem. Go look at the standard solutions to this.

of_get_mac_address(), eth_platform_get_mac_address(),
nvmem_get_mac_address(), of_get_mac_addr_nvmem(), etc.

Thank you! I will look on it!

Though in this case, it is not really a MAC, it is a BASE_MAC...
Maybe in DSA world this is usual?
