This is pretty much not the patch I was expecting to see.
I was expecting to see arch/powerpc/boot/dts/fsl/t1040rdb-rev-a.dts
containing only this:

/include/ t1040rdb.dts

/ {
	model = "fsl,T1040RDB-REV-A";
	compatible = "fsl,T1040RDB-REV-A";
};

&seville_port0 {
	label = "ETH5";
};

&seville_port2 {
	label = "ETH7";
};

&seville_port4 {
	label = "ETH9";
};

&seville_port6 {
	label = "ETH11";
};

Also, I don't see the changes from your original patch applied to the
main t1040rdb.dts. Did you forget to include them?
