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,
Danny Gale
