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-rg...@ef600b00 initialized with MDIO support
/plb/opb/emac-rg...@ef600b00: input 0 in RGMII mode
eth0: EMAC-0 /plb/opb/ether...@ef600900, MAC 00:47:41:52:52:59
/plb/opb/emac-rg...@ef600b00: input 1 in RGMII mode
/plb/opb/ether...@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
