+		Some boards require specialized initialization of the PHY before it
+		can be used.  This may include such things as configuring GPIOs,
+		resetting the PHY, etc.  If CONFIG_S32K1XX_ENET_PHYINIT is defined in
+		the configuration then the board specific logic must provide
+		imxrt_phy_boardinitialize();  The i.MXRT ENET driver will call this
+		function one time before it first uses the PHY.
