2017-11-21 Thread Paul Burton
Whilst the pcie_xilinx driver was sufficient to run under QEMU, it was failing on FPGA because it wasn't configuring the root bridge, and access from the PCI auto-configuration code to subordinate busses would lead to data bus errors. Fix this by configuring the root bridge to allow access to all p
