[edk2-devel] [PATCH v1 4/5] ArmVirtPkg: Enable ACPI support for Kvmtool

[PierreGondois]

From: Sami Mujawar <sami.mujawar at arm.com>

A Configuration Manager that uses the Dynamic Tables framework
to generate ACPI tables for Kvmtool Guests has been provided.
This Configuration Manager uses the FdtHwInfoParser module to
parse the Kvmtool Device Tree and generate the required
Configuration Manager objects for generating the ACPI tables.

Therefore, enable ACPI table generation for Kvmtool.
