I am seeing below panic with NUMA during DT mappings in

However, this issue is not there with 4.7 version. The same NUMA board
boots fine.
I am a bit confused by what you are saying. Xen on ARM does not yet support
NUMA. I also know you are working on NUMA support. So does the BUG happen on
upstream xen or upstream xen + your patches?
I was testing with Andre ITS patches (RFC version 1) + my NUMA patches
+ upstream xen.
However now I tested with upstream xen + Andre ITS patches (staging
branch) on NUMA board.
The RFC v1 is quite an old version. Please give a try using the latest
version [1].
I see panic (similar to what I see with my patches). Log are here.
Well the panic is different now. An ASSERT in list_del is hit this time.
This looks like a memory corruption to me.

The same plain upstream xen + Andre ITS patches boots fine with non-NUMA board.
I know that DOM0 cannot boot without ITS on your platform. But as you
don't reach DOM0, have you tried to boot without the ITS series on NUMA
board?
