True. But taking into account that the P4040 has 3 PCIe controllers not 4, I'd say it's a safe bet that the fact sheet PDF has it right and the P4081 has also 3 not 5.

The technical data and nomenclature provided by Freescale may be irritating at times, but "controllers" indeed means controllers here :-)
