166 * The SFE4001 does not power-up fully at reset due to its high power
167 * consumption. We control its power via a PCA9539 I/O expander.
168 * Both boards have a MAX6647 temperature monitor which we expose to
171 * This also provides minimal support for reflashing the PHY, which is
172 * initiated by resetting it with the FLASH_CFG_1 pin pulled down.
173 * On SFE4001 rev A2 and later this is connected to the 3V3X output of
174 * the IO-expander; on the SFN4111T it is connected to Falcon's GPIO3.
175 * We represent reflash mode as PHY_MODE_SPECIAL and make it mutually
176 * exclusive with the network device being open.
