Atom E3800 inbound PCI write to memory

[JHann]

Is it possible to map Atom E3800 (E3825) system memory to PCI memory space? I don't see anything in the Datasheet to support this.

I have a peripheral card on the PCI side of a PCI Express to PCI bridge that will initiate DMA transfers to PCI. I was hoping to initialize a BAR and remap so that these DMA writes target E3825 RAM.
