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

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

271 embedded CPUs made by Freescale. Selecting this option means that
272 you wish to build a kernel for a machine with a CPM2 coprocessor
273 on it (826x, 827x, 8560).
276 tristate "Axon DDR2 memory device driver"

280 It registers one block device per Axon's DDR2 memory bank found

282 minor numbers are available in /proc/devices, /proc/partitions or
283 in /sys/block/axonram?/dev.
