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
core, specific support for that chipset is asked later on.

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"

---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.

This option enables kernel support for the Signal Processing
Extensions (SPE) to the PowerPC processor. The kernel currently
