Hello, i have some problems to configure emac2, emac3 support of my ibm ppc440gx for linux kernel 2.6.11.6. I have two RGMII Phy?s connected to the ppc an no other PHY?s are connected. PPC Strapping is selected for Group4 (SMII, SMII, RGMII/RTBI, RGMII/RTBI). I only want to configure the RGMII support of emac2 and emac3. But it seems like the PHY?s are used for eth0 (emac1) and eth1 (emac2) which are configured as SMII. Could someone tell me, what i have to configure to select only emac2 and emac3 in RGMII mode?
