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.

powerpc

Documentation/feature-removal-schedule.txt says:
What: The arch/ppc and include/asm-ppc directories
When: Jun 2008
Why: The arch/powerpc tree is the merged architecture for ppc32 and ppc64
platforms. Currently there are efforts underway to port the remaining
arch/ppc platforms to the merged tree. New submissions to the arch/ppc
tree have been frozen with the 2.6.22 kernel release and that tree will
remain in bug-fix only mode until its scheduled removal. Platforms
that are not ported by June 2008 will be removed due to the lack of an
interested maintainer.

I see.
I'm doing "crossdev -t ia64" now.
More architectures to test (e.g. non-MMU arch) before submitting?
Thank you.
