This is a complete rework of the previous patch:
https://patchwork.kernel.org/project/xen-devel/patch/[email protected]/
v2:
- Split `implement setup_virt_paging for MPU system` into `arm/mpu:
implement setup_virt_paging for MPU system` and `Implement p2m tables`
- Rework register setup within `setup_virt_paging` to be more concise
- Introduce v8r_el1_msa device tree parameter
