          There are four types of PowerPC chips supported.  The more common
          types (601, 603, 604, 740, 750, 7400), the older Freescale
          (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
          52xx, 82xx, 83xx), the IBM embedded versions (403 and 405) and
          the Book E embedded processors from IBM (44x) and Freescale (85xx).
          For support for 64-bit processors, set ARCH=powerpc.
          Unless you are building a kernel for one of the embedded processor
          systems, choose 6xx.
          Also note that because the 52xx, 82xx, & 83xx family have a 603e

          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"

          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 TAU
        bool "Thermal Management Support"
        depends on 6xx && !8260 && !83xx
        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 || E200 || 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 KEXEC
        bool "kexec system call (EXPERIMENTAL)"
        depends on EXPERIMENTAL
        help
          kexec is a system call that implements the ability to shutdown your
          current kernel, and to start another kernel.  It is like a reboot
          but it is independent of the system firmware.   And like a reboot
          you can start any kernel with it, not just Linux.

          The name comes from the similarity to the exec system call.

          It is an ongoing process to be certain the hardware in a machine
          is properly shutdown, so do not be surprised if this code does not
          initially work for you.  It may help to enable device hotplugging
          support.  As of this writing the exact hardware interface is
          strongly in flux, so no good recommendation can be made.

          In the GameCube implementation, kexec allows you to load and
          run DOL files, including kernel and homebrew DOLs.

config PPC601_SYNC_FIX
        bool "Workarounds for PPC601 bugs"
        depends on 6xx && PPC_PREP
        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.

          4xx, 6xx, 7xx, 8xx, 74xx, and 82xx processors.  Currently, the

          This option will enable prompting for a variety of advanced kernel
          configuration options.  These options can cause the kernel to not
          work if they are set incorrectly, but can be used to optimize certain
          aspects of kernel memory management.

          Unless you know what you are doing, say N here.

          This option allows you to set the base address of the kernel virtual
          area used to map high memory pages.  This can be useful in
          optimizing the layout of kernel virtual memory.

          This option allows you to set the maximum amount of memory which
          will be used as "low memory", that is, memory which the kernel can
          access directly, without having to set up a kernel virtual mapping.
          This can be useful in optimizing the layout of kernel virtual
          memory.

          This option allows you to set the kernel virtual address at which
          the kernel will map low memory (the kernel image will be linked at
          this address).  This can be useful in optimizing the virtual memory
