          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.

        ---help---
          Cause the compiler to optimize for POWER4/POWER5/PPC970 processors.
          The resulting binary will not work on POWER3 or RS64 processors
          when compiled with binutils 2.15 or later.

        depends on PPC64
        help
          Cause the compiler to optimize for the PPE of the Cell Broadband
          Engine. This will make the code run considerably faster on Cell
          but somewhat slower on other machines. This option only changes
          the scheduling of instructions, not the selection of instructions
          itself, so the resulting kernel will keep running on all other
          machines. When building a kernel that is supposed to run only
          on Cell, you should also select the POWER4_ONLY option.

          This option enables kernel support for larger than 32-bit physical
          addresses.  This features is not be available on all e500 cores.

          If in doubt, say N here.

config ALTIVEC
        bool "AltiVec Support"
        depends on CLASSIC32 || POWER4
        ---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
        default y
        ---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 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).

          If in doubt, say Y here.

config VIRT_CPU_ACCOUNTING
        bool "Deterministic task and CPU time accounting"
        depends on PPC64
        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.
