The iommu mapping for S2 SIDs are taken care by TrustZone. For the targets which does not have the support of TrustZone, these mappings need to be created in the driver using an iommu domain. Leaving these SIDs unconfigured will result in a global smmu fault. Hence configuring them for Non-TrustZone targets is mandatory.
