There is a new variant 1 of this board available. It features up to four
SerDes lanes for customer use. Add a new device tree which features just
the basic peripherals. A customer will then have to modify or append to
this device tree.

That might fix it, but I don't want an old unused phy node in the device
tree
which isn't even there. Also I don't want one board starting the labels
with
phy0 and the other with phy1.
If you don't like that /delete-node/ stuff, I'd have to reorganize the
includes. var1 and var2 unfortunately isn't compatible with the base
variant
fsl-ls1028a-kontron-sl28.dts regarding the phy configurations. Thus I'd
probably have to split "fsl-ls1028a-kontron-sl28.dts" into a common dtsi
and
one which handles the networking.
