We are putting the o-scope on the board to look for hardware issues. Any help on what to look for concerning PCI hardware issues or my TLB / device tree issues would be highly appreciated - we're running out of time!
maybe I missed it but what's the issue?

No cards are recognized. We can, for example, put a Intel pro 100 ethernet card into a PC and see it recognized via lspci. Nothing we try shows any info for this card in dmesg or lspci, or any other card.
Make sure your clocks and resets are okay. - Then put only one device after each other on the pci bus (if possible) - check the IDSELects fit to the u-boot / kernel configuration - check the INT{A,B,C,D} fits to the IRQn# mapping to the kernel / the correct IDSELs.
See the pci@e0008000 { ... } entry in the device tree. This stuff has to fit to your hardware.
We are looking for clues and another set of eyes to see if we have software or hardware issues, or some combination.
Yes, it's the combination ;-)
