Tomasz Nowicki e0dad9a78c arm64: dts: marvell: keep SMMU disabled by default for Armada 7040 and 8040 ... commit f43cadef2df260101497a6aace05e24201f00202 upstream. FW has to configure devices' StreamIDs so that SMMU is able to lookup context and do proper translation later on. For Armada 7040 & 8040 and publicly available FW, most of the devices are configured properly, but some like ap_sdhci0, PCIe, NIC still remain unassigned which results in SMMU faults about unmatched StreamID (assuming ARM_SMMU_DISABLE_BYPASS_BY_DEFAUL=y). Since there is dependency on custom FW let SMMU be disabled by default. People who still willing to use SMMU need to enable manually and use ARM_SMMU_DISABLE_BYPASS_BY_DEFAUL=n (or via kernel command line) with extra caution.
