Hi,

Hi Edgar,


We're seeing panics in dom0 with PCIe enabled due to what seems
to be wrongly created mappings by Xen. With older kernels we
didn't see the panics but PCIe wasn't functional in dom0.

This disables the PCIe nodes on the ZynqMP until Xen/ARM gets
more PCIe support.

I feel a bit sad to ack a patch disabling PCIe in the ZynqMP.

Before doing that. Can you describe what is the exact problem with Xen? It might be possible that we don't parse correctly the device-tree.

Cheers,
