Oliver,
I recently shipped a PCIe design using Altera's Cyclone IV GX hard IP core. See the link below for the ref des that I used. Altera has several ref des for PCIe but I chose this one because I think it's rather intuitive and easier to add your custom logic to it. The DMA is not scatter-gather (it requires contiguous space) but this can serve as a baseline for your PCIe DMA design. Hope this help.

Hello, alybruin!
Are You sure, that AN 431: PCI Express to External Memory Reference Design has only simple DMA ( it requires contiguous space) without scatter-gather?
On page 8 of AN431 it is said: "The Qsys system contains PCIe, OnChipMem, DDR3, and
msgdma."
