Before this commit, makefiles under tools/ directory were implemented with their own way.

This commit refactors them by using "hostprogs-y" variable.

Several C sources have been added to wrap other C sources to simplify Makefile. For example, tools/crc32.c includes lib/crc32.c

This commit moves suffix rules from config.mk to scripts/Makefile.build, which will allow us to switch smoothly to real Kbuild.

Note1: post/lib_powerpc/fpu/Makefile has its own rule to compile C sources. We need to tweak it to keep the same behavior.

Note2: There are two file2 with the same name: arch/arm/lib/crt0.S and eamples/api/crt0.S. To keep the same build behavior, examples/api/Makefile also has to be treaked.

This commit adjusts some files to use Kbuild.include.

- Use cc-option defined in Kbuild.include (Delete cc-option in config.mk) - Use cc-version defined in (Delete cc-version in config.mk) - Move binutils-version and dtc-version to Kbuild.include by analogy to cc-version

This commit also adds srctree (same as SRCTREE) to use Kbuild scripts.

This commit changes the working directory where the build process occurs.

Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build.

That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot

Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build.

And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories.

On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending.

The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make.

Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory.

This patch seems a big change at a glance. But the idea is pretty simple.

The major change in the top Makefile is imported from Linux Kernel from Linux Kernel.

The rest parts are for adjusting prefixes.

- omit $(obj) prefixes for files which are generated in the top directory - change $(obj)foo to $(obj)/foo for files which are generated under sub directories. - add $(srctree)/ or $(src)/ prefixes when we need to point to the source files. - The environmanet BUILD_DIR has been renamed to KBUILD_OUTPUT. So, this commit modifies MAKEALL too.

FYI: Basic structure of the top Makefile is as follows:

ifeq ($(KBUILD_SRC),)

ifeq ("$(origin O)", "command line") KBUILD_OUTPUT := $(O) endif

ifneq ($(KBUILD_OUTPUT),)

<< define KBUILD_SRC and change directory and restart make >>

skip-makefile := 1 endif endif

ifeq ($(skip-makefile),)

<<Main part of Makefile>>

endif

Changes in v4: - Change a little checkstack target: Use $(src) rather than $(srctree) where Linux Kernel does so.

Changes in v3: - Rebase on the current u-boot/master

Changes in v2: - Rebase on v2014.01-rc2 tag - At version 1, sandbox got broken by this commit (and fixed again in the lator commit.) Fix this problem - Change a little MAKEALL Do not add "O=<dir>" if objtree is the same as srctree. This will be helpful at 35/35.

Some build scripts including scripts/Makefile.build will be imported from Linux Kernel in the next commit. We need to adjust them for U-Boot in the following commits.

To make it easier for reviewers to track the modification, this commit renames scripts/Makefile.build to scripts/Makefile.build.tmp beforehand.

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

Changes in v4: None Changes in v3: - Use "all:" instead of "__build:" in nand_spl Makefiles

This commit changes the location of include directives of board configuration files.

The purpose of this change is: - Slim down $(TOPDIR)/config.mk - Prevent $(TOPDIR)/Makefile from including the same configuration file twice - Do not include include/config.mk multiple times because ARCH, CPU, BOARD, VENDOR, SOC are exported

Before this commit:

- include/autoconf.mk was included from $(TOPDIR)/Makefile and $(TOPDIR)/config.mk (This means $(TOPDIR)/Makefile included include/autoconf.mk twice)

- include/{spl,tpl}-autoconf.mk was included from $(TOPDIR)/config.mk

- include/config.mk was included from $(TOPDIR)/Makefile and $(TOPDIR)/config.mk (This means $(TOPDIR)/Makefile included include/config.mk twice)

After this commit:

- include/autoconf.mk is included from $(TOPDIR)/Makefile and $(TOPDIR)/scripts/Makefile.build

- include/{spl,tpl}-autoconf.mk is included from $(TOPDIR)/spl/Makefile and $(TOPDIR)/scripts/Makefile.build

- include/config.mk is included from $(TOPDIR)/config.mk and $(TOPDIR)/spl/Makefile

Before this commit, "make tidy" did "make clean" + delete "*.depend*" files.

But, we do not have "*.depend*" files any more, which means "make tidy" is the same as "make clean".

This commit removes the redandant target "tidy".

$(MTD_VERSION) is used in tools/env/Makefile

If you specify a variable at a command line like: $ make MTD_VERSION=old env or specify it thru an envrionment variable like: $ export MTD_VERSION=old $ make env it is inherited to the sub-make too. We do not need to pass it from the top Makefile explicitely.

This commit fixes two problems:

[1] We could not do board configuration and "make all" in one command line.

For example, the following did not work as we expect: $ make sandbox_config all Configuring for sandbox board... make: Nothing to be done for `all'.

[2] mixed-target build did not work with -j option

For example, the following did not work: $ make -j8 sandbox_config u-boot Makefile:481: *** "System not configured - see README". Stop. make: *** [u-boot] Error 2 make: *** Waiting for unfinished jobs.... Configuring for sandbox board...

Going forward, we can do $ make -j8 sandbox_config all

This is the same as $ make sandbox_config $ make -j8

We had switched to Kbuild, so we do not need to delete sandburst board files at every build.

U-Boot conventional build system did not check the update of command line option, -DBUILDUSER.

Kbuild can handle it nicely and re-builds object files when command line options are changed. (The file ".*.cmd" stores the information how the file was generated at the previous build.)
