[edk2-devel] [PATCH v1 2/5] ArmVirtPkg: Add DSDT ACPI table for Kvmtool firmware

[PierreGondois]

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

Most ACPI tables for Kvmtool firmware are dynamically
generated. The AML code is also generated at runtime
for most components in appropriate SSDTs.

Although there may not be much to describe in the DSDT,
the DSDT table is mandatory.

Therefore, add an empty stub for DSDT.
