Just like for sc7180 devices using the Chrome bootflow (AKA trogdor and IDP), sc7280 devices using the Chrome bootflow also need their firmware marked dma-coherent. On sc7280 this wasn't causing WiFi to fail to startup, since WiFi works differently there. However, on sc7280 devices we were still getting the message at bootup after commit7bd6680b47("Revert "Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()"""): qcom_scm firmware:scm: Assign memory protection call failed -22 qcom_rmtfs_mem 9c900000.memory: assign memory failed qcom_rmtfs_mem: probe of 9c900000.memory failed with error -22 We should mark SCM properly just like we did for trogdor.
