The AM654x EVM based on the TI K3 family of SoCs has an updated board detection EEPROM structure that contains a TLV record of dedicated MAC addresses rather than a range of MAC addresses as it was used on earlier platforms such as DRA7. Add a basic function that allows us setting up Ethernet MAC addresses into the U-Boot environment based on the MAC address record contained in the common TI EEPROM structure.
