Hello,
these patches address some problems which prevent panfrost from working with Mali T628 GPUs:
- incomplete/incorrect mmu memory attributes - wrong jobs affinity on dual core group GPUs
With these patches panfrost is able to drive mali T628 (r1p0) GPU on some armv8 SoCs (in particular BE-M1000). r0 GPUs are still not supported [yet] (tested with Exynos 5422).
