	  There are five families of 32 bit PowerPC chips supported.
	  The most common ones are the desktop and server CPUs (601, 603,
	  604, 740, 750, 74xx) CPUs from Freescale and IBM, with their
	  embedded 52xx/82xx/83xx/86xx counterparts.
	  The other embeeded parts, namely 4xx, 8xx, e200 (55xx) and e500
	  (85xx) each form a family of their own that is not compatible
	  with the others.

	  If unsure, select 52xx/6xx/7xx/74xx/82xx/83xx/86xx.

config ALTIVEC

	---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 E200 || E500

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

config VIRT_CPU_ACCOUNTING
	bool "Deterministic task and CPU time accounting"

	default y
	help
	  Select this option to enable more accurate task and CPU time
	  accounting.  This is done by reading a CPU counter on each
	  kernel entry and exit and on transitions within the kernel
	  between system, softirq and hardirq state, so there is a
	  small performance impact.  This also enables accounting of
	  stolen time on logically-partitioned systems running on
	  IBM POWER5-based machines.

	  If in doubt, say Y here.

config SMP
	depends on PPC_STD_MMU
	bool "Symmetric multi-processing support"
	---help---
	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, say N. If you have a system with more
	  than one CPU, say Y.  Note that the kernel does not currently
	  support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
	  since they have inadequate hardware support for multiprocessor
	  operation.

	  If you say N here, the kernel will run on single and multiprocessor
	  machines, but will use only one CPU of a multiprocessor machine. If
	  you say Y here, the kernel will run on single-processor machines.
	  On a single-processor machine, the kernel will run faster if you say
	  N here.

	  If you don't know what to do here, say N.
