Are you > suggesting that we split the module into a built-in part and a modular part? I don't think entirely modular PCI root bridges should be a focal point for the design. If we happen to support them by other design choices: fine, but they should not be a priority. That being said if we have core dma mapping or PCIe code that has a list of offsets and the root complex only populates them it should work just fine.
