Re: [PATCH 10/12] xen/arm: if is_domain_direct_mapped use native UART address for vPL011

We always use a fix address to map the vPL011 to domains. The address

Instead, for domains that are directly mapped, reuse the address of the
physical UART on the platform to avoid potential clashes.

How do you know the physical UART MMIO region is big enough to fit the PL011?

What if the user want to assign the physical UART to the domain + the vpl011?
