[PATCH v2] iommu/arm-smmu-v3: Avoid ILLEGAL setting of STE.S1STALLD and CD.S

2017-09-21 Thread Yisheng Xie
According to Spec, it is ILLEGAL to set STE.S1STALLD if STALL_MODEL is not 0b00, which means we should not disable stall mode if stall or terminate mode is not configuable. Meanwhile, it is also ILLEGAL when STALL_MODEL==0b10 && CD.S==0 which means if stall mode is force we should always set CD.S.
