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

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

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

265 select PPC_PCI_CHOICE
266 select ARCH_REQUIRE_GPIOLIB
269 The CPM2 (Communications Processor Module) is a coprocessor on
270 embedded CPUs made by Freescale. Selecting this option means that
271 you wish to build a kernel for a machine with a CPM2 coprocessor
272 on it (826x, 827x, 8560).
275 tristate "Axon DDR2 memory device driver"
276 depends on PPC_IBM_CELL_BLADE && BLOCK
279 It registers one block device per Axon's DDR2 memory bank found
280 on a system. Block devices are called axonram?, their major and
281 minor numbers are available in /proc/devices, /proc/partitions or
282 in /sys/block/axonram?/dev.

315 bool "Support for simple, memory-mapped GPIO controllers"
318 select ARCH_REQUIRE_GPIOLIB
320 Say Y here to support simple, memory-mapped GPIO controllers.
321 These are usually BCSRs used to control board's switches, LEDs,
322 chip-selects, Ethernet/USB PHY's power and various other small
