The HiSilicon erratum 161010801 describes the limitation of HiSilicon platforms hip06/hip07 to support the SMMUv3 mappings for MSI transactions. PCIe controller on these platforms has to differentiate the MSI payload against other DMA payload and has to modify the MSI payload. This makes it difficult for these platforms to have SMMU translation for MSI. In order to workaround this, ARM SMMUv3 driver requires a quirk to treat the MSI regions separately. Such a quirk is currently missing for DT based systems and therefore we need to explicitly disable the hip06/hip07 smmu entries in dts.
