Yes, we tested the FF-A MM communication on the Corstone-1000 platform. We ran the UEFI SCT test suite containing EFI setVariable, getVariable and getNextVariable tests which involve FF-A MM communication and all tests are passing with the current changes. We made the SCT test reports (part of the ACS results) public following the latest Corstone-1000 release. Please find the test reports at [1].
