This seems to be a FDT/loader thing;  others will know more about what 
it means.

No it’s not pointless.  The more use cases we can make sure work, the 
better.



Testing SD cards would also be great to know they work well.

On a nanopi I am currently chasing (and running a disect):
- sdda sometimes created long after init started when running root from 
an mdimage
- very poor write performance on the SD (which wasn’t the case)
- a more-or-less random hang in g_waitidle when user space starts up
