From 8aab575c26e94c65b8cb3a44dc944c3c47ee1c07 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Wed, 1 Mar 2017 16:31:43 +0000 Subject: ArmVirtPkg: enable non-executable DXE stack for all platforms Now that ARM has grown support for managing memory permissions in ArmMmuLib, we can enable the non-executable DXE stack for all virt platforms. Note that this includes the AARCH64 Xen platform as well. Note that this is not [entirely] redundant: the non-executable stack is configured before DxeCore is invoked. The image and memory protection features configured during DXE only take affect when the CPU arch protocol implementation is registered.
