There's only one SoC on the Cyrus/X5000.

Actually, it's one PCIe-PCIe bridge with another PCIe-PCI bridge (for the PCI slots) attached to it.

I doubt Varisys simply forgot to use more than two PCIe controllers, but believe there is a good reason for using only two of them. It might be connected to the fact that the board has been designed for three different SoCs (P3041, P5020, P5040) which are not 100% pin-compatible, so the actual board design represents the lowest common denominator between the three SoCs.
http://morph.zone/modules/newbb_plus/viewtopic.php?forum=3&topic_id=7001&start=893Considering the fact that the P3041 version was abandoned anyway, they might as well have selected the P5021 instead of the P5020, as the P5021 and the P5040 are 100% pin-compatible.

Interesting. I didn't know that the CoreNet L3 cache can't be used also like a normal L3 cache. But even then this has nothing to do with the board design, don't you think?

Do you think this is a board design issue?

Do you think this is a board design issue?
