Just to let you all know:

we tried the N25Q512 with a StratixV and it is not working. A explanation could be that this is a stacked die device, and maybe thats why its not working. The quartus programmer says programming is complete, but verification fails and the flash is still empty afterwards (checked with a logic analyzer during configuration readout). We can write or read the flash with the ASMI parrallel IP core, but it looks like there the addressing is somehow wrong.

Anyway, we changed the flash to the N25Q256, and that one is working without any problems. We never tried the EPCQ512, because that one is far to expensive...
