[U-Boot] [PATCH v3 17/36] Kbuild: change out-of-tree build

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 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.
