214	help
215	  Some versions of the PPC601 (the first PowerPC chip) have bugs which
216	  mean that extra synchronization instructions are required near
217	  certain instructions, typically those that make major changes to the
218	  CPU state.  These extra instructions reduce performance slightly.
219	  If you say N here, these extra instructions will not be included,
220	  resulting in a kernel which will run faster but may not run at all
221	  on some systems with the PPC601 chip.
222
223	  If in doubt, say Y here.

225config TAU
226	bool "On-chip CPU temperature sensor support"
227	depends on CLASSIC32
228	help
229	  G3 and G4 processors have an on-chip temperature sensor called the
230	  'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
231	  temperature within 2-4 degrees Celsius. This option shows the current
232	  on-die temperature in /proc/cpuinfo if the cpu supports it.
233
234	  Unfortunately, on some chip revisions, this sensor is very inaccurate
235	  and in many cases, does not work at all, so don't assume the cpu
236	  temp is actually what /proc/cpuinfo says it is.
237
238config TAU_INT
239	bool "Interrupt driven TAU driver (DANGEROUS)"
240	depends on TAU
241	---help---
242	  The TAU supports an interrupt driven mode which causes an interrupt
243	  whenever the temperature goes out of range. This is the fastest way
244	  to get notified the temp has exceeded a range. With this option off,
245	  a timer is used to re-check the temperature periodically.
246
247	  However, on some cpus it appears that the TAU interrupt hardware
248	  is buggy and can cause a situation which would lead unexplained hard
249	  lockups.
250
251	  Unless you are extending the TAU driver, or enjoy kernel/hardware
252	  debugging, leave this option off.
253
254config TAU_AVERAGE
255	bool "Average high and low temp"
256	depends on TAU
257	---help---
258	  The TAU hardware can compare the temperature to an upper and lower
259	  bound.  The default behavior is to show both the upper and lower
260	  bound in /proc/cpuinfo. If the range is large, the temperature is
261	  either changing a lot, or the TAU hardware is broken (likely on some
262	  G4's). If the range is small (around 4 degrees), the temperature is
263	  relatively stable.  If you say Y here, a single temperature value,
264	  halfway between the upper and lower bounds, will be reported in
265	  /proc/cpuinfo.
266
267	  If in doubt, say N here.

284	help
285	  The CPM2 (Communications Processor Module) is a coprocessor on
286	  embedded CPUs made by Freescale.  Selecting this option means that
287	  you wish to build a kernel for a machine with a CPM2 coprocessor
288	  on it (826x, 827x, 8560).

296	  ioport callbacks or the platform device glue code.
