For pcie@a000, fsl_add_bridge(np, 0)?The old version of the code would call fsl_add_bridge(np, 1) for the host bridges @8000 and @a000. When I tried it that way, it=20 didn't work
What did not work? I tried two Ethernet cards @8000 and @a000. they worked..
I don't think you can have 2 primary bridges.
Why? They belong to two separate pci domain. Roy
