Hi,
I have a question on UEFI/ACPI tables setup and probing on arm64 platform.
Currently on arm64 platform guest can be booted with both fdt and ACPI
supported. If ACPI is enabled, [1] says the only defined method for
passing ACPI tables to the kernel is via the UEFI system configuration
table.
A helper struct AcpiCacheOffset is introduced to describe the offset
of three level caches. The cache hierarchy is built according to
ACPI spec v6.3 5.2.29.2. Let's enable CPU cache topology now.

MPIDR is consistent with CPU topology configured.

but the cpu property was enabled only for host-passthrough and
max cpu model. Let's add it for arm cpu which has the generic timer
