>Indeed, 23 of the 24 SerDes lanes of the PA6T on the Nemo/X1000 are assigned to PCIe
, while only max. 12 of 18 lanes are assignable to PCIe on the P5020 and even only max. 8 of 20 on the P5040. Freescale really didn't cover themselves in glory there.
It's probably related to the intended use of the CPUs. The PA6T was intended to be more of a general purpose processor, whereas the the Qorlq line is aimmed at communications devices.
