[Xen-devel] [PATCH v02 7/7] arm: add trap for remoteproc mmio accesses

[Andrii Tseglytskyi <andrii.tseglytskyi@xxxxxxxxxxxxxxx>]

The following patch connects already introduced
remoteproc iommu framework with existing trap framework.
Now, when kernel tries to access external MMU registers,
Xen triggers remoteproc iommu, which may perform
proper pfn to mfn translation.
