关于MMU中TTBR0保存的地址

thinkpad

对应arm v7a架构的MMU中寄存器TTBR0和TTBR1，
手册ARM® Architecture Reference Manual
ARMv7-A and ARMv7-R edition


B4.1.154 TTBR0, Translation Table Base Register 0, VMSA解释如下
TTBR0 holds the base address of translation table 0, and information about the memory it
occupies

我的问题是：
TTBR0和TTBR1中保存的地址是物理地址还是虚拟地址？

请大家帮忙看下！
