ARMv8 supports a range of physical address bit sizes. The PARange bits from ID_AA64MMFR0_EL1 register are read during boot-time and the intermediate physical address size bits are written in the translation control registers (TCR_EL1 and VTCR_EL2). There is no change in the VA bits and levels of translation.
