I'm not sure that you can. I had to write a simple driver for the PCIe CSB bridge dma on a 83xx ppc. I think that might be the one in the e500v2. I don't know how fast 'normal' PCIe slaves are, but we were accessing an Altera fpga and the latency is less than pedestrian. I think an ISA bus can run faster! With moderate length transfers, the throughput was more than adequate.
