Mali-G720 and Mali-G725 deprecates the use of FLUSH_MEM and FLUSH_PT MMU_AS commands in favour of cache maintenance via GPU_COMMAND's FLUSH_CACHES and FLUSH_PA_RANGE. They also introduce the following registers: - GPU_COMMAND_ARG0~1 - SHADER_PWRFEATURES - AMBA_FEATURES - AMBA_ENABLE This patch enables FLUSH_CACHES for both families of GPUs via the PANTHOR_HW_FEATURE_GPU_CTRL_CACHE_FLUSH bit until FLUSH_PA_RANGE support is added. It also adds the aforementioned register definitions and firmware binary support for arch 12.8 and 13.8.
