-  # "Map PCI MMIO as Cached"
-  #
-  # Due to the way Stage1 and Stage2 mappings are combined on Aarch64, and
-  # because KVM -- for the time being -- does not try to interfere with the
-  # Stage1 mappings, we must not set EFI_MEMORY_UC for emulated PCI MMIO
-  # regions.
-  #
-  # EFI_MEMORY_UC is mapped to Device-nGnRnE, and that Stage1 attribute would
-  # direct guest writes to host DRAM immediately, bypassing the cache
-  # regardless of Stage2 attributes. However, QEMU's reads of the same range
-  # can easily be served from the (stale) CPU cache.
-  #
-  # Setting this PCD to TRUE will use EFI_MEMORY_WB for mapping PCI MMIO
-  # regions, which ensures that guest writes to such regions go through the CPU
-  # cache. Strictly speaking this is wrong, but it is needed as a temporary
-  # workaround for emulated PCI devices. Setting the PCD to FALSE results in
-  # the theoretically correct EFI_MEMORY_UC mapping, and should be the long
-  # term choice, especially with assigned devices.
+  # Pure ACPI boot
   #
-  # The default is to turn off the kludge; DSC's can selectively enable it.
+  # Inhibit installation of the FDT as a configuration table if this feature
+  # PCD is TRUE. Otherwise, the OS is presented with both a DT and an ACPI
+  # description of the platform, and it is up to the OS to choose.
