Subject: [PATCH 3/3] ArmVirtPkg/ArmVirtQemu: add IncompatiblePciDeviceSupportDxe
Date: Mon, 12 Sep 2016 11:01:19 +0100	[thread overview]
Message-ID: <1473674479-20207-4-git-send-email-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <1473674479-20207-1-git-send-email-ard.biesheuvel@linaro.org>

To prevent the generic PCI bus driver from allocating 64-bit MMIO BARs in
the 32-bit region for no good reason (since no good reasons exist on ARM),
add the IncompatiblePciDeviceSupportDxe driver to the build, which will
force override the policy to do so in the presence of a ROM BAR.
