This series primarily moves more of the MSI, link up, and resource handling to the core code. Beyond a couple of minor fixes, new in this version is runtime detection of iATU regions instead of using DT properties. No doubt I've probably broken something. Please test. I've run this thru kernelci and checked boards with DWC PCI which currently is just Layerscape boards (hint: add boards and/or enable PCI). A git branch is here[1]. This is dependent on "PCI: dwc: Restore ATU memory resource setup to use last entry" which will be in v5.10-rc3.
