40 be selected by all platforms that need it.

43 bool "Support booting from Open Firmware or yaboot"
44 depends on 6xx || PPC64
47 Support from booting from Open Firmware or yaboot using an

49 communicate with open firmware to retrieve system informations
50 such as the device tree.

127 to not read back properly. It is safe to use on other chips as
128 well, but enabling it uses about 8KB of memory to keep copies

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

281 you wish to build a kernel for a machine with a CPM2 coprocessor
282 on it (826x, 827x, 8560).
285 tristate "Axon DDR2 memory device driver"
286 depends on PPC_IBM_CELL_BLADE && BLOCK
289 It registers one block device per Axon's DDR2 memory bank found

291 minor numbers are available in /proc/devices, /proc/partitions or
