kernel-doc: move kernel-doc tools to scripts/

2014-02-19T16:10:04Z

tools/kernel-doc/docproc.c and tools/kernel-doc/kernel-doc are files imported from Linux Kernel. They originally resided under scripts/ directory in Linux Kernel. This commit moves them to the original location. Signed-off-by: Masahiro Yamada Acked-by: Simon Glass

tools/env: cross-compile fw_printenv without setting HOSTCC

2014-02-19T16:10:04Z

fw_printenv is a program which mostly runs on the target Linux. Before switching to Kbuild, we needed to set HOSTCC at the command line like this: make HOSTCC= env Going forward we can cross compile it by specifying CROSS_COMPILE: make CROSS_COMPILE= env This looks more natural.

kbuild: use Linux Kernel build scripts

2014-02-19T16:07:50Z

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 some 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, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose. Signed-off-by: Masahiro Yamada Tested-by: Gerhard Sittig

kbuild: change out-of-tree build

2014-02-19T16:07:50Z

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 " 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=" syntax for descending into sub-directories. (We can write it like "make $(obj)=" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada Tested-by: Gerhard Sittig

Makefile: refactor include path settings

2014-02-19T16:07:50Z

This commit merges commonly-used header include paths to UBOOTINCLUDE and NOSTDINC_FLAGS variables, which are placed at the top Makefile. Signed-off-by: Masahiro Yamada

Makefile: move BFD_ROOT_DIR to tools/gdb/Makefile

2014-02-19T16:07:50Z

BFD_ROOT_DIR is used only in tools/gdb/Makefile Signed-off-by: Masahiro Yamada

tools: convert makefiles to kbuild style

2014-02-19T16:07:49Z

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 Signed-off-by: Masahiro Yamada
