[ Upstream commit 7372b944a6ba5ac86628eaacc89ed4f103435cb9 ]
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.
