-	default PCIE_BUS_DEFAULT
-	depends on EXPERT
-	help
-	  MPS (Max Payload Size) and MRRS (Max Read Request Size) are PCIe
-	  device parameters that affect performance and the ability to
-	  support hotplug and peer-to-peer DMA.
-
-	  The following choices set the MPS and MRRS optimization strategy
-	  at compile-time.  The choices are the same as those offered for
-	  the kernel command-line parameter 'pci', i.e.,
-	  'pci=pcie_bus_tune_off', 'pci=pcie_bus_safe',
-	  'pci=pcie_bus_perf', and 'pci=pcie_bus_peer2peer'.
-
-	  This is a compile-time setting and can be overridden by the above
-	  command-line parameters.  If unsure, choose PCIE_BUS_DEFAULT.
-
-config PCIE_BUS_TUNE_OFF
-	bool "Tune Off"
-	help
-	  Use the BIOS defaults; don't touch MPS at all.  This is the same
-	  as booting with 'pci=pcie_bus_tune_off'.
-
-config PCIE_BUS_DEFAULT
-	bool "Default"
-	help
-	  Default choice; ensure that the MPS matches upstream bridge.
-
-config PCIE_BUS_SAFE
-	bool "Safe"
-	help
-	  Use largest MPS that boot-time devices support.  If you have a
-	  closed system with no possibility of adding new devices, this
-	  will use the largest MPS that's supported by all devices.  This
-	  is the same as booting with 'pci=pcie_bus_safe'.
-
-config PCIE_BUS_PERFORMANCE
-	bool "Performance"
-	help
-	  Use MPS and MRRS for best performance.  Ensure that a given
-	  device's MPS is no larger than its parent MPS, which allows us to
-	  keep all switches/bridges to the max MPS supported by their
-	  parent.  This is the same as booting with 'pci=pcie_bus_perf'.
-
-config PCIE_BUS_PEER2PEER
-	bool "Peer2peer"
-	help
-	  Set MPS = 128 for all devices.  MPS configuration effected by the
-	  other options could cause the MPS on one root port to be
-	  different than that of the MPS on another, which may cause
-	  hot-added devices or peer-to-peer DMA to fail.  Set MPS to the
-	  smallest possible value (128B) system-wide to avoid these issues.
-	  This is the same as booting with 'pci=pcie_bus_peer2peer'.
