This was configured to use the deprecated CONFIG_OF_FLAT_TREE, change to CONFIG_OF_LIBFDT.
WARNING: This conversion is untested because I do not have a board to test it on.
NOTE: The FDT blob (DTS) must have an /aliases/ethernet0 and (optionally) /aliases/ethernet1 property for the ethernet to work.
