config 6xx
	bool "6xx/7xx/74xx/52xx/8260"
	help
	  There are four types of PowerPC chips supported.  The more common
	  types (601, 603, 604, 740, 750, 7400), the Motorola embedded
	  versions (821, 823, 850, 855, 860, 52xx, 8260), the IBM embedded
	  versions (403 and 405) and the high end 64 bit Power processors
	  (POWER 3, POWER4, and IBM 970 also known as G5)
	  Unless you are building a kernel for one of the embedded processor
	  systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx.
	  Note that the kernel runs in 32-bit mode even on 64-bit chips.
	  Also note that because the 52xx & 82xx family has a 603e core,
	  specific support for that chipset is asked later on.

config ALTIVEC
	bool "AltiVec Support"
	depends on 6xx || POWER4
	depends on !8260
	---help---
	  This option enables kernel support for the Altivec extensions to the
	  PowerPC processor. The kernel currently supports saving and restoring
	  altivec registers, and turning on the 'altivec enable' bit so user
	  processes can execute altivec instructions.

	  This option is only usefully if you have a processor that supports
	  altivec (G4, otherwise known as 74xx series), but does not have
	  any affect on a non-altivec cpu (it does, however add code to the
	  kernel).

	  If in doubt, say Y here.

config SPE
	bool "SPE Support"
	depends on E500
	---help---
	  This option enables kernel support for the Signal Processing
	  Extensions (SPE) to the PowerPC processor. The kernel currently
	  supports saving and restoring SPE registers, and turning on the
	  'spe enable' bit so user processes can execute SPE instructions.

	  This option is only usefully if you have a processor that supports
	  SPE (e500, otherwise known as 85xx series), but does not have any
	  affect on a non-spe cpu (it does, however add code to the kernel).

	  If in doubt, say Y here.

config TAU
	bool "Thermal Management Support"
	depends on 6xx && !8260
	help
	  G3 and G4 processors have an on-chip temperature sensor called the
	  'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
	  temperature within 2-4 degrees Celsius. This option shows the current
	  on-die temperature in /proc/cpuinfo if the cpu supports it.

	  Unfortunately, on some chip revisions, this sensor is very inaccurate
	  and in some cases, does not work at all, so don't assume the cpu
	  temp is actually what /proc/cpuinfo says it is.

config TAU_INT
	bool "Interrupt driven TAU driver (DANGEROUS)"
	depends on TAU
	---help---
	  The TAU supports an interrupt driven mode which causes an interrupt
	  whenever the temperature goes out of range. This is the fastest way
	  to get notified the temp has exceeded a range. With this option off,
	  a timer is used to re-check the temperature periodically.

	  However, on some cpus it appears that the TAU interrupt hardware
	  is buggy and can cause a situation which would lead unexplained hard
	  lockups.

	  Unless you are extending the TAU driver, or enjoy kernel/hardware
	  debugging, leave this option off.

config TAU_AVERAGE
	bool "Average high and low temp"
	depends on TAU
	---help---
	  The TAU hardware can compare the temperature to an upper and lower
	  bound.  The default behavior is to show both the upper and lower
	  bound in /proc/cpuinfo. If the range is large, the temperature is
	  either changing a lot, or the TAU hardware is broken (likely on some
	  G4's). If the range is small (around 4 degrees), the temperature is
	  relatively stable.  If you say Y here, a single temperature value,
	  halfway between the upper and lower bounds, will be reported in
	  /proc/cpuinfo.

	  If in doubt, say N here.

config MATH_EMULATION
	bool "Math emulation"
	depends on 4xx || 8xx || E500
	---help---
	  Some PowerPC chips designed for embedded applications do not have
	  a floating-point unit and therefore do not implement the
	  floating-point instructions in the PowerPC instruction set.  If you
	  say Y here, the kernel will include code to emulate a floating-point
	  unit, which will allow programs that use floating-point
	  instructions to run.

	  If you have an Apple machine or an IBM RS/6000 or pSeries machine,
	  or any machine with a 6xx, 7xx or 7xxx series processor, say N
	  here.  Saying Y here will not hurt performance (on any machine) but
	  will increase the size of the kernel.

config CPU_FREQ
	bool "CPU Frequency scaling"
	help
	  Clock scaling allows you to change the clock speed of CPUs on the
	  fly. This is a nice method to save battery power on notebooks,
	  because the lower the clock speed, the less power the CPU consumes.

	  For more information, take a look at <file:Documentation/cpu-freq> or
	  at <http://www.brodo.de/cpufreq/>

	  If in doubt, say N.

config CPU_FREQ_PMAC
	bool "Support for Apple PowerBooks"
	depends on CPU_FREQ && ADB_PMU
	help
	  This adds support for frequency switching on Apple PowerBooks,
	  this currently includes some models of iBook & Titanium
	  PowerBook.

config CPU_FREQ_TABLE
	bool
	depends on CPU_FREQ_PMAC
	default y

config PPC601_SYNC_FIX
	bool "Workarounds for PPC601 bugs"
	depends on 6xx && (PPC_PREP || PPC_PMAC)
	help
	  Some versions of the PPC601 (the first PowerPC chip) have bugs which
	  mean that extra synchronization instructions are required near
	  certain instructions, typically those that make major changes to the
	  CPU state.  These extra instructions reduce performance slightly.
	  If you say N here, these extra instructions will not be included,
	  resulting in a kernel which will run faster but may not run at all
	  on some systems with the PPC601 chip.

	  If in doubt, say Y here.
