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.
+ embedded 512x/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.

+ 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.
