I tested it successfully on cubieboard 1GB, on top of kernel 3.10-rc3,
nfsroot (debian wheezy)
I also added in sun4i-a10-cubieboard.dts
phy0: ethernet-phy@0 {
reg = <1>;
},
like Emilio suggested.
running an iperf, there's some good perfs !
iperf -s

That's great ! with this patchset, we can now run a server with a
vanilla kernel ( who needs more that a serial port and ethernet,
really ? ;) )
