AM3352配置DP83848K问题

TI大神们，

    在下现在调试网络芯片DP83848K遇到问题，U-BOOT中调试修改如下：

   默认ID为0x01

static struct cpsw_slave_data cpsw_slaves[] = {
{
.slave_reg_ofs = 0x208,
.sliver_reg_ofs = 0xd80,
.phy_id = 1,
},
{
.slave_reg_ofs = 0x308,
.sliver_reg_ofs = 0xdc0,
.phy_id = 0,
},
};

board_eth_init()函数中设置了模式为mii

writel(MII_MODE_ENABLE, &cdev->miisel);
cpsw_slaves[0].phy_if = cpsw_slaves[1].phy_if =
PHY_INTERFACE_MODE_MII;

ping_mux中初始化为：

configure_module_pin_mux(mii1_pin_mux);

打印如下：
musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn)
