<div>Hi, </div>
<div> </div>
<div>I am a newbie to PowerPC architecture and eTSEC. I have some queries:</div>
<div> </div>
<div>1. Is there a way for me to configure different eTSECs in different media modes? I understand that the MII interface does the same thing; yet do I have to take some explicit care in the drivers for the eTSEC to differentiate between a copper and fiber interface? Is this task of the SW or is this configuration basically by the HW.</div>
<div> </div>
<div>2. My custom board has the TSECs connected to a Marvell switch; one of the ports being connected via the RGMII interface to a copper media; whilst the other connected via the RGMII interface to another port on the switch via the SGMII interface. Do I need to make any changes in the driver to effect this configuration. I referred the gianfar, mdio, phy, mii drivers; but couldnt find any specific code which would enable me to differentiate the media interfaces.</div>
<div> </div>
<div>3. My HW team tells me to write specific values to the PHY registers which will differentiate the media interfaces to the Marvell switch via the MDIO/MDCTL configuration lines from the MPC. If this is the case,</div>
<div>a. Would it be recommended to implement a PHY-ID specific implementation for writing to the PHY registers in the gfar_enet_open when the phy_connect function is called? OR</div>
<div>b. Would it be recommended to pass some kind of member through the DTS file to the kernel, therbey affecting a change in the platform specific file.</div>
<div> </div>
<div>Can any one please help me clear off these queries?</div>
<div> </div>
<div>Thanx!</div>
