Newby trying to get Ethernet going on MPC83xx series device.

[Aggrwal Poonam-B10812]

Can you look into your board specific file 
Like board/freescale/mpc8249_mds/mpc8349_mds.c

And check if the buses are getting probed.

For example

static struct of_device_id mpc834x_ids[] = {
        { .type = "soc", },
        { .compatible = "soc", },
        { .compatible = "simple-bus", },
        {},
};

static int __init mpc834x_declare_of_platform_devices(void)
{
        of_platform_bus_probe(NULL, mpc834x_ids, NULL);
        return 0;
}
machine_device_initcall(mpc834x_mds,
mpc834x_declare_of_platform_devices);

Regards
Poonam
