+ 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

+ help
+ This enables code to use a new device tree binding for describing CPU

+ If you're not sure say Y.

+ 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.

+ 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

+ 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

+ select CPM
+ select HAVE_PCI
+ 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
+ select GENERIC_ISA_DMA

+ 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.

+ 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.
