/** @file
A hook-in library for MdeModulePkg/Universal/Acpi/AcpiTableDxe.
Plugging this library instance into AcpiTableDxe makes
EFI_ACPI_TABLE_PROTOCOL and (if enabled) EFI_ACPI_SDT_PROTOCOL depend on the
platform's dynamic decision whether to expose an ACPI-based hardware
description to the operating system.
Universal and platform specific DXE drivers that produce ACPI tables depend
on EFI_ACPI_TABLE_PROTOCOL / EFI_ACPI_SDT_PROTOCOL in turn.
