[time passes] OK, I have a patch that seems for work as far as setting PPC32=y or PPC64=y... but it has a problem during linking of vmlinux: crosstool/gcc-9.3.0-nolibc/powerpc-linux/bin/powerpc-linux-ld:./arch/powerpc/kernel/vmlinux.lds:6: syntax error and the (bad) generated vmlinux.lds file says (at line 6): OUTPUT_ARCH(1:common) while it should say: OUTPUT_ARCH(powerpc:common) Does anyone have any ideas about this problem?
The following change fixes the problem, allthough I guess that's not what you want to do at the end. diff --git a/scripts/Makefile.build b/scripts/Makefile.build index 1b6094a13034..00f72699c518 100644 --- a/scripts/Makefile.build +++ b/scripts/Makefile.build @@ -358,7 +358,7 @@ targets += $(lib-y) $(always-y) $(MAKECMDGOALS) # Linker scripts preprocessor (.lds.S -> .lds) # --------------------------------------------------------------------------- quiet_cmd_cpp_lds_S = LDS $@ - cmd_cpp_lds_S = $(CPP) $(cpp_flags) -P -U$(ARCH) \ + cmd_cpp_lds_S = $(CPP) $(cpp_flags) -P -U$(SRCARCH) \ -D__ASSEMBLY__ -DLINKER_SCRIPT -o $@ $< $(obj)/%.lds: $(src)/%.lds.S FORCE
The ARCH=ppc32 / ARCH=ppc64 patch is below FYI. It is missing an update to Documentation/kbuild/kbuild.rst (aliases). thanks.
