  	  The MPIC global timer is a hardware timer inside the

  	  This option enables a MPIC driver workaround for some chips

  config PPC601_SYNC_FIX
  	bool "Workarounds for PPC601 bugs"
  	depends on 6xx && 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.
  
  config TAU
  	bool "On-chip CPU temperature sensor support"
  	depends on 6xx
  	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 many 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 QUICC_ENGINE
  	bool "Freescale QUICC Engine (QE) Support"

  	help
  	  The QUICC Engine (QE) is a new generation of communications
  	  coprocessors on Freescale embedded CPUs (akin to CPM in older chips).
  	  Selecting this option means that you wish to build a kernel
  	  for a machine with a QE coprocessor.

  	  Say Y here to support simple, memory-mapped GPIO controllers.
