I see you used some FSL embedded board. Do you have your PCIe MMIO space above 32-bit ? Last I looked, there was a bunch of fixing needing to be done, among others in the TTM, to make that work. I had some preliminary patches but they bitrot... mostly the issue is to make sure than a phys_addr_t is used instead of an unsigned long whenever it tries to store the physical address of an object.
