Hm, actually not that surprising if it was working without the offset
adjustments and doing non-aligned mappings -- perhaps the nvme code just
needs to round the offsets down instead of expecting swiotlb to do it?
Note I didn't look at that part of the code at all, so I might be
stating the obvious in a way that's difficult to adjust...

The one I have is included in the iMX8MP and iMX8MQ socs, the later is
included in the mnt reform and librem 5 and both have evaluation
toolkits but I wouldn't quite say they are easy to get...
I'm happy to test different patch variants if Horia doesn't beat me to
it though, it's not as practical as having the device but don't hesitate
to ask if I can run with extra debugs or something.
