We are still stumped on this one, but during a review of the system
setup one thing came up that we aren't sure about is the device tree
and the DMA engine.

It does seem that for incoming PCI transactions the Freescale DMA
engine is not used.  And in our device tree we have the DMA engine
commented out.  That is, the "fsl,mpc8349-dma" and "fsl,elo-dma"
compatible items are not present in the FDT.

I don't suppose this could be a problem?

I doubt it but somebody from FSL might be able to give a better answer.

I'm personally at a loss. It looks like you are doing everything
right from what I can tell.

That leaves us with some kind of oddball driver bug or a problem
with the low level configuration of the PCIe bridge or the chip
internal bus related to cache coherency maybe.
