26 depends on 6xx || PPC64
28 Support for running natively on the hardware, i.e. without
29 a hypervisor. This option is not user-selectable but should
30 be selected by all platforms that need it.
32 config PPC_OF_BOOT_TRAMPOLINE
33 bool "Support booting from Open Firmware or yaboot"
34 depends on 6xx || PPC64
37 Support from booting from Open Firmware or yaboot using an
38 Open Firmware client interface. This enables the kernel to
39 communicate with open firmware to retrieve system informations
40 such as the device tree.
42 In case of doubt, say Y

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

173 This adds the support for frequency switching on PA Semi
174 PWRficient processors.
178 config PPC601_SYNC_FIX
179 bool "Workarounds for PPC601 bugs"
180 depends on 6xx && (PPC_PREP || PPC_PMAC)
182 Some versions of the PPC601 (the first PowerPC chip) have bugs which
183 mean that extra synchronization instructions are required near
184 certain instructions, typically those that make major changes to the
185 CPU state. These extra instructions reduce performance slightly.
186 If you say N here, these extra instructions will not be included,
187 resulting in a kernel which will run faster but may not run at all
188 on some systems with the PPC601 chip.
190 If in doubt, say Y here.
193 bool "On-chip CPU temperature sensor support"
196 G3 and G4 processors have an on-chip temperature sensor called the
197 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
198 temperature within 2-4 degrees Celsius. This option shows the current
199 on-die temperature in /proc/cpuinfo if the cpu supports it.
201 Unfortunately, on some chip revisions, this sensor is very inaccurate
202 and in many cases, does not work at all, so don't assume the cpu
203 temp is actually what /proc/cpuinfo says it is.
206 bool "Interrupt driven TAU driver (DANGEROUS)"
209 The TAU supports an interrupt driven mode which causes an interrupt
210 whenever the temperature goes out of range. This is the fastest way
211 to get notified the temp has exceeded a range. With this option off,
212 a timer is used to re-check the temperature periodically.
214 However, on some cpus it appears that the TAU interrupt hardware
215 is buggy and can cause a situation which would lead unexplained hard
218 Unless you are extending the TAU driver, or enjoy kernel/hardware
219 debugging, leave this option off.
222 bool "Average high and low temp"
225 The TAU hardware can compare the temperature to an upper and lower
226 bound. The default behavior is to show both the upper and lower
227 bound in /proc/cpuinfo. If the range is large, the temperature is
228 either changing a lot, or the TAU hardware is broken (likely on some
229 G4's). If the range is small (around 4 degrees), the temperature is
230 relatively stable. If you say Y here, a single temperature value,
231 halfway between the upper and lower bounds, will be reported in
234 If in doubt, say N here.
237 bool "Freescale QUICC Engine (QE) Support"
242 The QUICC Engine (QE) is a new generation of communications
243 coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
244 Selecting this option means that you wish to build a kernel
245 for a machine with a QE coprocessor.
248 bool "QE GPIO support"
249 depends on QUICC_ENGINE
251 select ARCH_REQUIRE_GPIOLIB

257 bool "Enable support for the CPM2 (Communications Processor Module)"
258 depends on MPC85xx || 8260
261 select PPC_PCI_CHOICE
262 select ARCH_REQUIRE_GPIOLIB
265 The CPM2 (Communications Processor Module) is a coprocessor on
266 embedded CPUs made by Freescale. Selecting this option means that
267 you wish to build a kernel for a machine with a CPM2 coprocessor
268 on it (826x, 827x, 8560).
271 tristate "Axon DDR2 memory device driver"
272 depends on PPC_IBM_CELL_BLADE
275 It registers one block device per Axon's DDR2 memory bank found
276 on a system. Block devices are called axonram?, their major and
277 minor numbers are available in /proc/devices, /proc/partitions or
278 in /sys/block/axonram?/dev.
283 select GENERIC_ISA_DMA
285 Supports for the ULI1575 PCIe south bridge that exists on some
286 Freescale reference boards. The boards all use the ULI in pretty
296 Uses information from the OF or flattened device tree to instatiate
297 platform devices for direct mapped RTC chips like the DS1742 or DS1743.

311 bool "Support for simple, memory-mapped GPIO controllers"
314 select ARCH_REQUIRE_GPIOLIB
316 Say Y here to support simple, memory-mapped GPIO controllers.
317 These are usually BCSRs used to control board's switches, LEDs,
318 chip-selects, Ethernet/USB PHY's power and various other small
319 on-board peripherals.

327 Say Y here to enable soft power-off functionality on the Freescale
328 boards with the MPC8349E-mITX-compatible MCU chips. This driver will
329 also register MCU GPIOs with the generic GPIO API, so you'll able
330 to use MCU pins as GPIOs.
