I'm looking to do some prototype work, trying to leverage some existing custom I/O modules (multiprotocol serial, GPIO, some proprietary and rare buses, etc.) from my company to the iMX53x.
The modules are PCI interface to their normal host boards (PPC and Intel boards), but we want to see if we can link them up with the iMX53x as well.
So, anyone have any thoughts about using the External Memory Interface (or ???) to talk PCI (not PCIe) to these expansion modules?
