In old days, Linux supported PowerPC with two arch directories,
arch/ppc/ and arch/ppc64/.
Linux commit 564ee7a5668e ("[PATCH] powerpc: Move arch/ppc*/kernel/vecemu.c
to arch/powerpc") started the migration to arch/powerpc/, and
commit 917f0af9e5a9 ("powerpc: Remove arch/ppc and include/asm-ppc")
finished it.
This commit aligns the directory name with the current Linux.
I did 'git mv arch/ppc/ arch/powerpc/', and fixed up some hard-coded
arch/ppc paths.
Barebox has stuck to arch/ppc/ for a long time. To keep the backward
compatibility, I added the following to the top Makefile.
# Support ARCH=ppc for backward compatibility
ifeq ($(ARCH),ppc)
SRCARCH := powerpc
endif
Both ARCH=ppc and ARCH=powerpc work in the same way.
