Try this code to do the loop test.

#if defined(CONFIG_YOURBOARD)
#define MAX_PHY_ADDR    64
        for (i = 0 ; i < MAX_PHY_ADDR; i++) {
                macb->phy_addr = i;
                phy_id = macb_mdio_read(macb, MII_PHYSID1);
                if (phy_id != 0xffff)
                        break;
        }
        printf("phy_id %x found at %d\n", phy_id, i);
#else
        phy_id = macb_mdio_read(macb, MII_PHYSID1);
#endif
