* Universal/Acpi/AcpiTableDxe Implementation of EFI_ACPI_TABLE_PROTOCOL (MdePkg/Include/Protocol/AcpiTable.h) * Universal/Acpi/AcpiPlatformDxe Sample "ACPI Platform Driver" which populates the system ACPI tables by reading them from an FFS file and using EFI_ACPI_TABLE_PROTOCOL to make them available to the system. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@7917 6f19259b-4bc3-4df7-8a09-765794883524
