I don't want to interfere, however I would like to contribute my opinion as an end user of PCI_MVEBU. I have been using Linux on a custom built hardware with an Armada A388, for several years, and to me the most critical component for getting PCIe working right in Linux is the u-boot version. Although I've stopped trying the official u-boot releases as well as the SoM vendor u-boot versions, because I don't have much time available to tinker with those, however the ones I have tried always failed to bring a working PCIe environment under Linux. So I am stuck with a u-boot based on the Marvel release 2013.01. It was key to getting PCIe working in Linux, other than that, all Linux kernels have worked fine and I have been using an AMD RX550 PCIe dGPU and a DVB-T/DVB-S PCIe tuner card simultaneously, each in its own slot, without issues for all these years.
