I'm trying to work out how to setup my custom dts file to support dual ethernet.
This is on a custom board based on the BeagleBone, but with both ethernet ports
connected in MII mode.
So far I have just copied the layout of am335x-evm.dts, but that only gives me
eth0:-

I added:-
mac: ethernet@4a100000 {
dual_emac = <1>;
};
... which gives me eth0 and eth1, but kills my nfs root:-

I know this should work (since the svm has dual ethernet), so can anyone give
me some pointers ?
Cheers
