Nvme timeout on warm boot when switching sodimm

We only changed fsl-lx2160a.dtsi once following our previous discussion here:

Pci kernel panic when upgrading to latest

We’re trying to pin point the problem in the current xdma driver in order to understand exactly what is causing the panic. In the old dts, pcie3 had only one range of 0x9040000000 memory configured in the dts: ranges = <0x82000000 0x0 0x40000000 0x90 0x40000000 0x0 0x40000000>; /* non-prefetchable memory */ In the new dts, pcie3 now has three entries: ranges = <0x43000000 0xa4 0x00000000 0x94 0x00000000 0x04 0x00000000>, /* 64-Bit Window - prefetchable / <0x02000000 0x00 0x40000000 0x90 0x…

You helped us there do this single fix:

Do we need to do something similar in the other controllers?
