* Function: stm32_ethinitialize
|
|
*
|
|
* Description:
|
|
* Initialize the Ethernet driver for one interface. If the STM32 chip
|
|
* supports multiple Ethernet controllers, then board specific logic must
|
|
* implement arm_netinitialize() and call this function to initialize the
|
|
* desired interfaces.
|
|
*
|
|
* Input Parameters:
|
|
* intf - In the case where there are multiple EMACs, this value
|
|
* identifies which EMAC is to be initialized.
|
|
*
|
|
* Returned Value:
|
|
* OK on success; Negated errno on failure.
|
|
*
|

* Function: stm32_phy_boardinitialize
|
|
*
|
|
* Description:
|
|
* 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_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.
|
|
*
|
|
* Input Parameters:
|
|
* intf - Always zero for now.
|
|
*
|
|
* Returned Value:
