* The SFE4001 does not power-up fully at reset due to its high power

* Both boards have a MAX6647 temperature monitor which we expose to
* the lm90 driver.
*
* This also provides minimal support for reflashing the PHY, which is
* initiated by resetting it with the FLASH_CFG_1 pin pulled down.
* On SFE4001 rev A2 and later this is connected to the 3V3X output of
* the IO-expander; on the SFN4111T it is connected to Falcon's GPIO3.
* We represent reflash mode as PHY_MODE_SPECIAL and make it mutually
