Well, I was looking at an older tree. If you are using of_device for
TSEC, the most likely cause of this problem is that
of_platform_bus_probe() didn't probe your ethernet nodes.
Refer to the following code in
arch/powerpc/platforms/83xx/mpc834x_itx.c. Make sure it creates
of_platform_device for TSEC.
static struct of_device_id __initdata mpc834x_itx_ids[] = {
{ .compatible = "fsl,pq2pro-localbus", },
{ .compatible = "simple-bus", },
{},
};
static int __init mpc834x_itx_declare_of_platform_devices(void)
{
return of_platform_bus_probe(NULL, mpc834x_itx_ids, NULL);
}
machine_device_initcall(mpc834x_itx,
mpc834x_itx_declare_of_platform_devices);
