Start from mt6779, INVLDT_SEL move to offset=0x2c, so we add REG_MMU_INV_SEL_GEN2 definition and mt6779 uses it. 2. Change PROTECT_PA_ALIGN from 128 byte to 256 byte. 3. For REG_MMU_CTRL_REG register, we only need to change bit[2:0], others bits keep default value, ex: enable victim tlb. 4. Add mt6779_data to support mm_iommu HW init.
