AM625: use iic1 read eeprom mac

Part Number: AM625
Other Parts Discussed in Thread: SK-AM62

Tool/software:

Purpose:
Referring to the method of using iic0 to read MAC in sk-AM62, I would like to modify uboot to implement iic1 to read MAC and bind it to eth1.
Problem:

During the process of viewing the uboot source code, the following code was found
ret = ti_i2c_eeprom_am6_get_base(CONFIG_EEPROM_BUS_ADDRESS,CONFIG_EEPROM_CHIP_ADDRESS);

Is it possible to implement the function by modifying VNet EEPROM_SUS_ADDRESS=1, but I haven't found where it is defined. Is it necessary to define it in uboot/config/am62x_evm_a53_defconfig?
