Subject: [PATCH 4/4] ArmVirtPkg: enable PE/COFF image and memory protection for ARM platforms
Date: Wed, 1 Mar 2017 14:42:24 +0000 [thread overview]
Message-ID: <1488379344-16273-5-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1488379344-16273-1-git-send-email-ard.biesheuvel@linaro.org>
Like for AARCH64, enable PE/COFF image and NX memory protection for all
32-bit ARM virt platforms.
Note that this does not [yet] protect EfiLoaderData regions, due to
compatibility issues with GRUB.
