[PATCH v1 0/3] xen/arm: Add option to optionally disable trapping on unmapped mmio

["Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxx>]

From: "Edgar E. Iglesias" <edgar.iglesias@xxxxxxx>

This follows up on the virtio-pci discussion and adds a per-domain
option to select the behaviour of accesses to unmapped mmio ranges.
The new option is trap-unmapped-mmio. For dom0less I negated it to
be able to use a boolean prop and keep existing behaviour, i.e
trap-unmapped-mmio-disabled.

I'm happy with any name though so if you have better ideas please
suggest them!

For the domain config i followed the example of x86 flags
and XEN_X86_MSR_RELXED, creating a flags field for ARM.

Thanks,
Edgar
