config KVM_GUEST bool"KVM Guest support"
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"
help
Enables ePAPR para-virtualization support for guests.
In case of doubt, say Y
config PPC_HASH_MMU_NATIVE bool
depends on PPC_BOOK3S
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 PPC_BOOK3S_32 || PPC64
select RELOCATABLE if 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 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 IPIC bool
config MPIC bool
config MPIC_TIMER bool"MPIC Global Timer"
depends on MPIC && FSL_SOC
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
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_MSGR bool"MPIC message register support"
depends on MPIC
help
Enables support for the MPIC message registers. These
registers are used for inter-processor communication.

config RTAS_PROC bool"Proc interface to RTAS"
depends on PPC_RTAS && PROC_FS default y
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 TAU bool"On-chip CPU temperature sensor support"
depends on PPC_BOOK3S_32
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

Say Y here if you're going to use hardware that connects to the
QE GPIOs.

depends on (FSL_SOC_BOOKE && PPC32) || PPC_82xx
select CPM
select HAVE_PCI
select GPIOLIB
select OF_GPIO_MM_GPIOCHIP
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"ULI1575 PCIe south bridge support"

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

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 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.
