Beside the other comment for the pfe nodes, the nodes themselves have
problems. DTC is spitting out messages like this:
Warning (reg_format): "reg" property in /pfe at 04000000/ethernet at 0 has
invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)
Warning (reg_format): "reg" property in /pfe at 04000000/ethernet at 1 has
invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)
Warning (ranges_format): "ranges" property in /pfe at 04000000 has
invalid length (32 bytes) (parent #address-cells == 2, child
#address-cells == 2, #size-cells == 1)
Warning (avoid_default_addr_size): Relying on default #address-cells

Warning (avoid_default_addr_size): Relying on default #size-cells

Ditto for the nodes in other board dts.
