Subject: [PATCH v4 7/7] ArmVirtPkg/ArmVirt.dsc.inc: enable NX memory protection for all platforms
Date: Mon, 27 Feb 2017 14:38:11 +0000	[thread overview]
Message-ID: <1488206291-25768-8-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1488206291-25768-1-git-send-email-ard.biesheuvel@linaro.org>

This sets the recently introduced PCD PcdDxeNxMemoryProtectionPolicy to
a value that protects all memory regions except code regions against
inadvertent execution.
