5.修改网卡驱动，支持phy ar8033
（1）根据单板修改phy地址
P1010BOARD.h：
#define TSEC1_PHY_ADDR 1
#define TSEC2_PHY_ADDR 6/*0->6*/
#define TSEC3_PHY_ADDR 4/*2->4*/
增加宏
Miiphyutil.c (...\u-boot\common) 42:
#define MII_DEBUG
编译烧写，调试log如下：
Net: miiphy_register: added 'eTSEC1', read=0x3ff618d8, write=0x3ff61884
eTSEC1: No support for PHY id ffffffff; assuming generic
miiphy_register: added 'eTSEC2', read=0x3ff618d8, write=0x3ff61884
eTSEC2: No support for PHY id 4dd074; assuming generic
miiphy_register: added 'eTSEC3', read=0x3ff618d8, write=0x3ff61884
eTSEC3: No support for PHY id 4dd074; assuming generic
eTSEC1, eTSEC2, eTSEC3

=>
u-boot不支持单板的phy,分析phy启动增加phy ar8033支持
（2）分析phy驱动
start.S
bl board_init_r
puts ("Net: ");
eth_initialize (bd);
miiphy_init();
board_eth_init
tsec_eth_init(bis, tsec_info, num);
tsec_initialize(bis, &tsecs[i]);
eth_register(dev);
miiphy_register(dev->name, tsec_miiphy_read, tsec_miiphy_write);
debug ("miiphy_register: added '%s', read=0x%08lx, write=0x%08lx\n",
new_dev->name, new_dev->read, new_dev->write);
init_phy(dev);
get_phy_info(dev);
/* loop through all the known PHY types, and find one that */
/* matches the ID we read from the PHY. */
for (i = 0; phy_info[i]; i++) {
if (phy_info[i]->id == (phy_ID >> phy_info[i]->shift)) {
theInfo = phy_info[i];
break;
}
}
Tsec.c (.....\u-boot-2010.12\drivers\net) 57620 2015/5/18
phy_info数组没有支持ar8033,增加phy支持：
add:
struct phy_info phy_info_AR8033 = {
0x4dd074,
"AR8033",
0,
(struct phy_cmd[]) { /* config */
{PHY_BMCR, PHY_BMCR_RESET, NULL},
{PHY_BMCR, PHY_BMCR_AUTON|PHY_BMCR_RST_NEG, NULL},
{0x1d, 0x05, NULL},
{0x1e, 0x3D47, NULL},
{miim_end,}
},
(struct phy_cmd[]) { /* startup */
{PHY_BMSR, miim_read, NULL},
{PHY_BMSR, miim_read, &mii_parse_sr},
{PHY_BMSR, miim_read, &mii_parse_link},
{miim_end,}
},
(struct phy_cmd[]) { /* shutdown */
{miim_end,}
}
};
static struct phy_info *phy_info[] = {
2060 add:
&phy_info_AR8033,
重新编译，烧写调试：
