I understand since we lost all arm32 boards in OSSTest so it is not likely for a GICv2 series to progress, but this series passed our internal CI on all GICv2 boards and it would be good to have some feedbacks so that I can make the series ready to be committed before the arm32 boards are re-added to OSSTest. Thanks very much! Kind regards, Henry
