Programming PHY firmware over MDIO

We are working with the Broadcom BCM84834 PHY (4-port 10G-BASE-T) being controlled by a Freescale T4240. The 84834 needs firmware in order to operate. The device can either load its firmware from MDIO or from a SPI EEPROM. Once loaded via MDIO, the PHY can write its new firmware to EEPROM for future use.

Where is the appropriate place in u-boot to do this firmware download? Is it at the end of board_eth_init?

Is there a mechanism in place to do this kind of firmware load already? I didn't see one looking through the code.

Thanks,
