It is convenient to have all device trees on the same SoC compiled. It allows for later easy repackaging without the need to re-run the make file. - Build device trees with the same SoC under arch/$(ARCH)/dts - Copy the one specified by CONFIG_DEFAULT_DEVICE_TREE or DEVICE_TREE=... to dts/dt.dtb Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

Unlike Linux Kernel, U-Boot historically had *.dts files under board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/. I think arch/$(ARCH)/dts dicretory is a better location to store both *.dts and *.dtsi files. For example, before this commit, board/xilinx/dts directory had both Microblaze dts (microblaze-generic.dts) and ARM dts (zynq-*.dts), which are totally unrelated. This commit moves *.dts to arch/$(ARCH)/dts/ directories, allowing us to describe nicely mutiple DTBs generation in the next commit. Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

Useful rules in scripts/Makefile.lib allows us to easily generate a device tree blob and wrap it in assembly code. We do not need to parse a linker script to get output format and arch. This commit deletes ./u-boot.dtb since it is a copy of dts/dt.dtb. Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

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=<your CC cross-compiler> env Going forward we can cross compile it by specifying CROSS_COMPILE: make CROSS_COMPILE=<your cross-compiler prefix> env This looks more natural.

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.)

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 Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

This commit refactors cleaning targets such as clean, clobber, mrpropper, distclean with scripts/Makefile.clean. By using scripts/Makefile.clean, we can recursively descend into subdirectories and delete generated files there. We do not need add a big list of generated files to the "clean" target.

$(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.

This commit changes the top Makefile to handle various targets nicely. Make targets are divided into four categories: - mixed-targets We can call a configuration target and build targets at one command line like follows: $ make <board_name>_config u-boot They are handled one by one. - config targets <board_name>_config - no-dot-config-targets Targets we can run without board configuration such as clean, mrproper, distclean, TAGS, %docs, etc. - build targets The other target which need board configuration.

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". Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

Before this commit, {spl,tpl}-autoconf.mk was always generated at the top Makefile even if SPL(TPL) build was not selected. This commit moves the build rule of {spl,tpl}-autoconf.mk from the top Makefile to spl/Makefile. It prevents unnecessary {spl,tpl}-autoconf.mk from being generated.

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 Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

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.

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. Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: NGerhard Sittig <gsi@denx.de>

Before this commit, most of compiler flags were defined in config.mk. But it is redundant because config.mk is included from all recursive make. This commit moves many complier flags to the top Makefile and export them. And we use new vaiarables to store them: KBUILD_CPPFLAGS, KBUILD_CFLAGS, KBUILD_AFLAGS. This will allow us to switch more smoothly to Kbuild. Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

This commit moves some variable definitions from config.mk to the top Makefile: - HOSTCC, HOSTCFLAGS, HOSTLDFLAGS - AS, LD, CC, CPP, etc. - SHELL (renamed to CONFIG_SHELL) I'd like to slim down config.mk file because it is included from all recursive make. It is redundant to re-define the variables every time descending into sub directories. We should rather define them at the top Makefile and export them. U-Boot makefiles has been used "SHELL" variable to store shell chosen for the user, whereas Linux Kernel uses "CONFIG_SHELL". We should never use "SHELL" variable because it is a special variable for GNU Make. Changing SHELL may cause unpredictable side effects whose root cause is usually difficult to find. We should use a generic variable name "CONFIG_SHELL". We should not use the syntax as follows either: rm -f $(obj)tools/env/{fw_printenv,fw_setenv} This depends on "bash" although GNU Make generally invokes "sh" to run the each rule.

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.
