Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust build scripts for U-Boot. But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally. Instead, there are ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o for that purpose.
Signed-off-by: Masahiro Yamada yamada.m@jp.panasonic.com ---
Please note that we are not allowed to change CFLAGS locally.
See the following snippet from scripts/Makefile.build
# If the save-* variables changed error out ifeq ($(KBUILD_NOPEDANTIC),) ifneq ("$(save-cflags)","$(CFLAGS)") $(error CFLAGS was changed in "$(kbuild-file)". Fix it to use ccflags-y) endif endif
If you are not familiar with Kbuild style makefiles, I recommend you to read the document in Linux Kernel: Documentation/kbuild/makefiles.txt
