When enabling the APPS SMMU the mainline driver reconfigures the SMMU from its bootloader configuration, losing the stream mapping for (among which) the SDHCI hardware and breaking its ADMA feature. This feature can be disabled with: sdhci.debug_quirks=0x40 But it is of course desired to have this feature enabled and working through the SMMU.
