From 253a2ea73fe0a3a02177c25930c289df77e122b2 Mon Sep 17 00:00:00 2001 From: jljusten Date: Tue, 31 Jul 2012 18:17:51 +0000 Subject: OvmfPkg: install an SSDT with a dynamic OperationRegion called FWDT "FWDT" ("firmware data") is allocated as EfiReservedMemoryType, with AllocateReservedPool(). doesn't seem to provide direct access to EfiACPIReclaimMemory, but at this point the former seems sufficient.
