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