From: Andreas Gaeer <andreas.g...@baslerweb.com>
Without this change the MAC address only gets properly set when the
ethaddr is already set in u-boot environment.
Now the board setup should do the following:
1. Put a valid ethaddr into environment (eg. by I2C EEPROM)
2. Call dv_set_mac_address() to set the address in TI EMAC driver
