---help---
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
STM32_PHYINIT is defined in the configuration then the board specific logic must
provide stm32_phyinitialize(); The STM32 Ethernet driver will call this function
one time before it first uses the PHY.
