201 bool "Workarounds for PPC601 bugs"
202 depends on 6xx && (PPC_PREP || PPC_PMAC)
204 Some versions of the PPC601 (the first PowerPC chip) have bugs which
205 mean that extra synchronization instructions are required near
206 certain instructions, typically those that make major changes to the
207 CPU state. These extra instructions reduce performance slightly.
208 If you say N here, these extra instructions will not be included,
209 resulting in a kernel which will run faster but may not run at all
210 on some systems with the PPC601 chip.
212 If in doubt, say Y here.
215 bool "On-chip CPU temperature sensor support"
218 G3 and G4 processors have an on-chip temperature sensor called the
219 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
220 temperature within 2-4 degrees Celsius. This option shows the current
221 on-die temperature in /proc/cpuinfo if the cpu supports it.
223 Unfortunately, on some chip revisions, this sensor is very inaccurate
224 and in many cases, does not work at all, so don't assume the cpu
225 temp is actually what /proc/cpuinfo says it is.
228 bool "Interrupt driven TAU driver (DANGEROUS)"
231 The TAU supports an interrupt driven mode which causes an interrupt
232 whenever the temperature goes out of range. This is the fastest way
233 to get notified the temp has exceeded a range. With this option off,
234 a timer is used to re-check the temperature periodically.
236 However, on some cpus it appears that the TAU interrupt hardware
237 is buggy and can cause a situation which would lead unexplained hard
240 Unless you are extending the TAU driver, or enjoy kernel/hardware
241 debugging, leave this option off.
244 bool "Average high and low temp"
247 The TAU hardware can compare the temperature to an upper and lower
248 bound. The default behavior is to show both the upper and lower
249 bound in /proc/cpuinfo. If the range is large, the temperature is
250 either changing a lot, or the TAU hardware is broken (likely on some
251 G4's). If the range is small (around 4 degrees), the temperature is
252 relatively stable. If you say Y here, a single temperature value,
253 halfway between the upper and lower bounds, will be reported in
256 If in doubt, say N here.
261 The QUICC Engine (QE) is a new generation of communications
262 coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
263 Selecting this option means that you wish to build a kernel
264 for a machine with a QE coprocessor.
270 The CPM2 (Communications Processor Module) is a coprocessor on
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"
277 depends on PPC_IBM_CELL_BLADE
280 It registers one block device per Axon's DDR2 memory bank found
281 on a system. Block devices are called axonram?, their major and
282 minor numbers are available in /proc/devices, /proc/partitions or
283 in /sys/block/axonram?/dev.
288 select GENERIC_ISA_DMA

291 Freescale reference boards. The boards all use the ULI in pretty
