Subject: [PATCH 2/2] Split HSM & IFSI into separate IOMMU groups
Patch-mainline: Never, downstream fix.
References: jsc#EB-390

In order for HSM & IFSI to work in parallel
split the two functions up into separate IOMMU groups.

We have agreed that the change is tested for specific 
workload so potential harm should be negligible. 
But it is a non-upstream (and likely not upstreamable solution) 
and we cannot really carry it for ever so a different approach 
has to be adopted for future products based on a different base kernel.

Elektrobit is responsible for this patch.
