[PATCH v3 4/4] ArmVirtPkg: enable PE/COFF image and memory protection for ARM platforms

[Ard Biesheuvel <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.
