Hello all：

We use the AMCC PowerPC 405ex through emac1 way RGMII with realtek RTL8211 Giga phy linked to, At present the PHY Address is: 00110

add delay  2ns for RGMII

CONFIG[8:5]:AUTO_Negotiation

1111=NWay,advertise ，all capabilities,prefer Slave

mode;1=RGMII mode

Clk on the hardware no problem, Mdio, mdc even on, but at Llinux / driver / net / ibm-newemac / core.c discovered phy address, phy ID at  .Config file has joined

NETDEVICE = Y

PHYLIB=Y

                                             REALTEK-PHY=Y

But will be compiled under the best Uimage to board, the feeling of the PHY the driver has not been mounted use. The following is a kernel information

  PPC 4xx OCP EMAC driver, version 3.54

MAL v2 /plb/mcmal, 2 TX channels, 2 RX channels

RGMII /plb/opb/emac-rgmii@ef600b00 initialized with MDIO support

/plb/opb/emac-rgmii@ef600b00: input 0 in RGMII mode

eth0: EMAC-0 /plb/opb/ethernet@ef600900, MAC 00:47:41:52:52:59

/plb/opb/emac-rgmii@ef600b00: input 1 in RGMII mode

/plb/opb/ethernet@ef600a00: find TRL 821X Giga PHY（0x4）

But also in Llinux / driver / net / ibm-newemac / phy.c also add the operation of RTL8211bg as follows:

#define RTL821x_PHYSR            0x11

#define RTL821x_PHYSR_DUPLEX    0x2000

#define RTL821x_PHYSR_SPEED       0xc000

#define RTL821x_INER        0x12

#define RTL821x_INER_INIT      0x6400

#define RTL821x_INSR        0x13

static int rtl821x_init(struct mii_phy *phy)

{

       phy_write(phy, RTL821x_INER, 0x6400); //enable interrupt

              return  0;

}

static struct mii_phy_ops rtl821x_phy_ops = {

       .init         = rtl821x_init,

       .setup_aneg    = genmii_setup_aneg,

       .setup_forced  = genmii_setup_forced,

       .poll_link = genmii_poll_link,

       .read_link       = genmii_read_link

};

static struct mii_phy_def rtl821x_phy_def = {

       .phy_id           = 0x001cc912,  // for rtl8211 single phy

   // .phy_id         = 0x001cc960,   for 8366sr inside phy 4

       .phy_id_mask = 0x001fffff,

       .name             = "RTL 821X Giga Phy",

       .features  = PHY_GBIT_FEATURES,

       //.flags           = PHY_HAS_INTERRUPT,

       .ops        = &rtl821x_phy_ops

But will be compiled under the best Uimage to board, the feeling of the PHY the driver has not been mounted use. The following is a kernel information
