From a0ae9c7c05b969cbaffb0371f8698c54465b4c96 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 13 Jun 2007 02:30:17 +1000 Subject: [POWERPC] Split out CPU specific options into a new Kconfig file A lot of the options in arch/powerpc/Kconfig deal with the CPU menu, and my next patches add more to them. Moving them to a new arch/powerpc/platforms/Kconfig.cputype file makes it easier to follow. There are no functional changes in here.

Therefore, this patch removes the fragments of APUS support code from arch/powerpc which have been copied from arch/ppc. A few APUS references are left in asm-powerpc in .h files which are still used from arch/ppc.
