+config KVM_GUEST
+	bool "KVM Guest support"
+	default n
+	select EPAPR_PARAVIRT
+	---help---
+	  This option enables various optimizations for running under the KVM
+	  hypervisor. Overhead for the kernel when not running inside KVM should
+	  be minimal.
+
+	  In case of doubt, say Y
+
+config EPAPR_PARAVIRT
+	bool "ePAPR para-virtualization support"
+	default n
+	help
+	  Enables ePAPR para-virtualization support for guests.
+
+	  In case of doubt, say Y
+
+config PPC_NATIVE
+	bool
+	depends on 6xx || PPC64
+	help
+	  Support for running natively on the hardware, i.e. without
+	  a hypervisor. This option is not user-selectable but should
+	  be selected by all platforms that need it.
+
+config PPC_OF_BOOT_TRAMPOLINE
+	bool "Support booting from Open Firmware or yaboot"
+	depends on 6xx || PPC64
+	default y
+	help
+	  Support from booting from Open Firmware or yaboot using an
+	  Open Firmware client interface. This enables the kernel to
+	  communicate with open firmware to retrieve system information
+	  such as the device tree.
+
+	  In case of doubt, say Y
+
+config PPC_DT_CPU_FTRS
+	bool "Device-tree based CPU feature discovery & setup"
+	depends on PPC_BOOK3S_64
+	default y
+	help
+	  This enables code to use a new device tree binding for describing CPU
+	  compatibility and features. Saying Y here will attempt to use the new
+	  binding if the firmware provides it. Currently only the skiboot
+	  firmware provides this binding.
+	  If you're not sure say Y.
+
+config UDBG_RTAS_CONSOLE
+	bool "RTAS based debug console"
+	depends on PPC_RTAS
+	default n
+
+config PPC_SMP_MUXED_IPI
+	bool
+	help
+	  Select this option if your platform supports SMP and your
+	  interrupt controller provides less than 4 interrupts to each
+	  cpu.	This will enable the generic code to multiplex the 4
+	  messages on to one ipi.
+

+config MPIC
+	bool
+	default n
+
+config MPIC_TIMER
+	bool "MPIC Global Timer"
+	depends on MPIC && FSL_SOC
+	default n
+	help
+	  The MPIC global timer is a hardware timer inside the
+	  Freescale PIC complying with OpenPIC standard. When the
+	  specified interval times out, the hardware timer generates
+	  an interrupt. The driver currently is only tested on fsl
+	  chip, but it can potentially support other global timers
+	  complying with the OpenPIC standard.
+
+config FSL_MPIC_TIMER_WAKEUP
+	tristate "Freescale MPIC global timer wakeup driver"
+	depends on FSL_SOC &&  MPIC_TIMER && PM
+	default n
+	help
+	  The driver provides a way to wake up the system by MPIC
+	  timer.
+	  e.g. "echo 5 > /sys/devices/system/mpic/timer_wakeup"
+

+config MPIC_BROKEN_REGREAD
+	bool
+	depends on MPIC
+	help
+	  This option enables a MPIC driver workaround for some chips
+	  that have a bug that causes some interrupt source information
+	  to not read back properly. It is safe to use on other chips as
+	  well, but enabling it uses about 8KB of memory to keep copies
+	  of the register contents in software.

+config PPC601_SYNC_FIX
+	bool "Workarounds for PPC601 bugs"
+	depends on 6xx && PPC_PMAC
+	help
+	  Some versions of the PPC601 (the first PowerPC chip) have bugs which
+	  mean that extra synchronization instructions are required near
+	  certain instructions, typically those that make major changes to the
+	  CPU state.  These extra instructions reduce performance slightly.
+	  If you say N here, these extra instructions will not be included,
+	  resulting in a kernel which will run faster but may not run at all
+	  on some systems with the PPC601 chip.
+
+	  If in doubt, say Y here.
+
+config TAU
+	bool "On-chip CPU temperature sensor support"
+	depends on 6xx
+	help
+	  G3 and G4 processors have an on-chip temperature sensor called the
+	  'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
+	  temperature within 2-4 degrees Celsius. This option shows the current
+	  on-die temperature in /proc/cpuinfo if the cpu supports it.
+
+	  Unfortunately, this sensor is very inaccurate when uncalibrated, so
+	  don't assume the cpu temp is actually what /proc/cpuinfo says it is.
+
+config TAU_INT
+	bool "Interrupt driven TAU driver (EXPERIMENTAL)"
+	depends on TAU
+	---help---
+	  The TAU supports an interrupt driven mode which causes an interrupt
+	  whenever the temperature goes out of range. This is the fastest way
+	  to get notified the temp has exceeded a range. With this option off,
+	  a timer is used to re-check the temperature periodically.
+
+	  If in doubt, say N here.
+
+config TAU_AVERAGE
+	bool "Average high and low temp"
+	depends on TAU
+	---help---
+	  The TAU hardware can compare the temperature to an upper and lower
+	  bound.  The default behavior is to show both the upper and lower
+	  bound in /proc/cpuinfo. If the range is large, the temperature is
+	  either changing a lot, or the TAU hardware is broken (likely on some
+	  G4's). If the range is small (around 4 degrees), the temperature is
+	  relatively stable.  If you say Y here, a single temperature value,
+	  halfway between the upper and lower bounds, will be reported in
+	  /proc/cpuinfo.
+
+	  If in doubt, say N here.
+
+config QE_GPIO
+	bool "QE GPIO support"
+	depends on QUICC_ENGINE
+	select GPIOLIB
+	help
+	  Say Y here if you're going to use hardware that connects to the
+	  QE GPIOs.
+
+config CPM2
+	bool "Enable support for the CPM2 (Communications Processor Module)"
+	depends on (FSL_SOC_BOOKE && PPC32) || 8260
+	select CPM
+	select PPC_PCI_CHOICE
+	select GPIOLIB
+	help
+	  The CPM2 (Communications Processor Module) is a coprocessor on
+	  embedded CPUs made by Freescale.  Selecting this option means that
+	  you wish to build a kernel for a machine with a CPM2 coprocessor
+	  on it (826x, 827x, 8560).
+
+config FSL_ULI1575
+	bool
+	default n
+	select GENERIC_ISA_DMA
+	help
+	  Supports for the ULI1575 PCIe south bridge that exists on some
+	  Freescale reference boards. The boards all use the ULI in pretty
+	  much the same way.
+
+config CPM
+	bool
+	select GENERIC_ALLOCATOR
+
+config OF_RTC
+	bool
+	help
+	  Uses information from the OF or flattened device tree to instantiate
+	  platform devices for direct mapped RTC chips like the DS1742 or DS1743.
+
+config GEN_RTC
+	bool "Use the platform RTC operations from user space"
+	select RTC_CLASS
+	select RTC_DRV_GENERIC
+	help
+	  This option provides backwards compatibility with the old gen_rtc.ko
+	  module that was traditionally used for old PowerPC machines.
+	  Platforms should migrate to enabling the RTC_DRV_GENERIC by hand
+	  replacing their get_rtc_time/set_rtc_time callbacks with
+	  a proper RTC device driver.
+
+config SIMPLE_GPIO
+	bool "Support for simple, memory-mapped GPIO controllers"
+	depends on PPC
+	select GPIOLIB
+	help
+	  Say Y here to support simple, memory-mapped GPIO controllers.
+	  These are usually BCSRs used to control board's switches, LEDs,
+	  chip-selects, Ethernet/USB PHY's power and various other small
+	  on-board peripherals.
+
+config MCU_MPC8349EMITX
+	bool "MPC8349E-mITX MCU driver"
+	depends on I2C=y && PPC_83xx
+	select GPIOLIB
+	help
+	  Say Y here to enable soft power-off functionality on the Freescale
+	  boards with the MPC8349E-mITX-compatible MCU chips. This driver will
+	  also register MCU GPIOs with the generic GPIO API, so you'll able
+	  to use MCU pins as GPIOs.
+
+config XILINX_PCI
+	bool "Xilinx PCI host bridge support"
+	depends on PCI && XILINX_VIRTEX
