[PATCH v2 1/7] iommu/arm-smmu-v3: Introduce SMMU option PAGE0_REGS_ONLY

2017-05-04 Thread Geetha sowjanya
From: Linu Cherian Cavium ThunderX2 SMMU implementation doesn't support page 1 register space and PAGE0_REGS_ONLY option will be enabled as an errata workaround. This option when turned on, replaces all page 1 offsets used for EVTQ_PROD/CONS, PRIQ_PROD/CONS register access with page 0 offsets.
