How do arch/ppc and arch/powerpc differ?

[Tetsuo Handa]

Hello.

According to Documentation/SubmitChecklist,
ppc64 is a good architecture for cross-compilation checking.
I've just set up cross compiling environment for ppc64
using "crossdev -t ppc64" on Gentoo 2007.0 environment.

Now I'm trying to modify Makefile to build kernel for ppc64.
I've got a question here.

  ARCH            ?= powerpc
  CROSS_COMPILE   ?= powerpc64-unknown-linux-gnu-

Which keyword ("ppc" or "powerpc") do I need to set for ARCH
to do cross-compilation checking?
How do they differ?

Regards.
