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. # # Signed-off-by: Masahiro Yamada # Signed-off-by: Michael
