Commit Message

Karunika Choo March 20, 2025, 11:17 a.m. UTC
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.
