Masahiro Yamada 4ba7f80f42 powerpc/boot: pass CONFIG options in a simpler and more robust way Commit `5e9dcb6188` ("powerpc/boot: Expose Kconfig symbols to wrapper") was wrong, but commit `e41b93a6be` ("powerpc/boot: Fix build failures with -j 1") was also wrong. The correct dependency is: $(obj)/serial.o: $(obj)/autoconf.h However, I do not see the reason why we need to copy autoconf.h to arch/power/boot/. Nor do I see consistency in the way of passing CONFIG options. decompress.c references CONFIG_KERNEL_GZIP and CONFIG_KERNEL_XZ, which are passed via the command line. serial.c includes autoconf.h to reference a couple of CONFIG options, but this is fragile because we often forget to include "autoconf.h" from source files. In fact, it is already broken. ppc_asm.h references CONFIG_PPC_8xx, but utils.S is not given any way to access CONFIG options. So, CONFIG_PPC_8xx is never defined here. Pass $(LINUXINCLUDE) to make sure CONFIG options are accessible from all .c and .S files in arch/powerpc/boot/. I also removed the -traditional flag to make include/linux/kconfig.h work. This flag makes the preprocessor imitate the behavior of the pre-standard C compiler, but I do not understand why it is necessary.

To extract the kernel vmlinux, System.map, .config or initrd from the zImage binary:

objcopy -j .kernel:vmlinux -O binary zImage vmlinux.gz
objcopy -j .kernel:System.map -O binary zImage System.map.gz
objcopy -j .kernel:.config -O binary zImage config.gz
objcopy -j .kernel:initrd -O binary zImage.initrd initrd.gz
