A branch is here[1]. I've noticed that with the latest linux-next, my board doesn't boot anymore. I've traced it back to this series. There is a similar board in kernelci [1,2] where you can have a look at the backtrace. I've bisected this to the following patch: PCI: dwc: Use generic config accessors I'm pretty much lost here. It seems that the kernel tries to read from an invalid/unmapped memory address.
