2015-03-28kbuild: remove scripts/multiconfig.shMasahiro Yamada
We have switched to the single .config configuration system, the same one as used in Linux Kernel. The necessary glue code is small enough now, so move it to the top-level Makefile and scripts/kconfig/Makefile, and then delete scripts/multiconfig.sh.

2015-03-28kbuild: remove "*_felconfig" targetMasahiro Yamada
This target was added by commit cbdd9a9737cc (sunxi: kconfig: Add %_felconfig rule to enable FEL build of sunxi platforms.). At that time, U-Boot used separate .config files for U-Boot proper and SPL. I understood the pain to modify both .config and spl/.config. Now, we have switched to single .config configuration. It seems acceptable to run "make menuconfig" or friends to enable CONFIG_SPL_FEL, as we do for other CONFIGs.

2015-02-24kconfig: switch to single .config configurationMasahiro Yamada
When Kconfig for U-boot was examined, one of the biggest issues was how to support multiple images (Normal, SPL, TPL). There were actually two options, "single .config" and "multiple .config". After some discussions and thought experiments, I chose the latter, i.e. to create ".config", "spl/.config", "tpl/.config" for Normal, SPL, TPL, respectively. It is true that the "multiple .config" strategy provided us the maximum flexibility and helped to avoid duplicating CONFIGs among Normal, SPL, TPL, but I have noticed some fatal problems: [1] It is impossible to share CONFIG options across the images. If you change the configuration of Main image, you often have to adjust some SPL configurations correspondingly. Currently, we cannot handle the dependencies between them. It means one of the biggest advantages of Kconfig is lost. [2] It is too painful to change both ".config" and "spl/.config". Sunxi guys started to work around this problem by creating a new configuration target. Commit cbdd9a9737cc (sunxi: kconfig: Add %_felconfig rule to enable FEL build of sunxi platforms.) added "make *_felconfig" to enable CONFIG_SPL_FEL on both images. Changing the configuration of multiple images in one command is a generic demand. The current implementation cannot propose any good solution about this. [3] Kconfig files are getting ugly and difficult to understand. Commit b724bd7d6349 (dm: Kconfig: Move CONFIG_SYS_MALLOC_F_LEN to Kconfig) has sprinkled "if !SPL_BUILD" over the Kconfig files. [4] The build system got more complicated than it should be. To adjust Linux-originated Kconfig to U-Boot, the helper script "scripts/multiconfig.sh" was introduced. Writing a complicated text processor is a shell script sometimes caused problems. Now I believe the "single .config" will serve us better. With it, all the problems above would go away. Instead, we will have to add some CONFIG_SPL_* (and CONFIG_TPL_*) options such as CONFIG_SPL_DM, but we will not have much. Anyway, this is what we do now in scripts/Makefile.spl. I admit my mistake with my apology and this commit switches to the single .config configuration. It is not so difficult to do that: - Remove unnecessary processings from scripts/multiconfig.sh This file will remain for a while to support the current defconfig format. It will be removed after more cleanups are done. - Adjust some makefiles and Kconfigs - Add some entries to include/config_uncmd_spl.h and the new file scripts/Makefile.uncmd_spl. Some CONFIG options that are not supported on SPL must be disabled because one .config is shared between SPL and U-Boot proper going forward. I know this is not a beautiful solution and I think we can do better, but let's see how much we will have to describe them. - update doc/README.kconfig More cleaning up patches will follow this.

2015-02-21kbuild: prepare for moving headers into mach-*/include/machMasahiro Yamada
In U-Boot, SoC-specific headers are placed in arch/$(ARCH)/include/asm/arch-$(SOC) and a symbolic link to that directory is created at the early stage of the build process. Creating and removing a symbolic link during the build is not preferred. In fact, Linux Kernel did away with include/asm-$(ARCH) directories a long time time ago. As for ARM, now it is possible to collect SoC sources into arch/arm/mach-$(SOC). It is also reasonable to move SoC headers into arch/arm/mach-$(SOC)/include/mach. This commit prepares for that. If the directory arch/$(ARCH)/mach-$(SOC)/include/mach exists, a symbolic to that directory is created. Otherwise, a symbolic link to arch/$(ARCH)/include/asm/arch-$(SOC) or arch-$(CPU) is created.

2015-01-14sunxi: Fix CONFIG_UART0_PORT_F build and add it to menuconfigSiarhei Siamashka
The CONFIG_UART0_PORT_F option has been supported since http://git.denx.de/?p=u-boot.git;a=commit;h=ff2b47f6a9cc1025 This option is primarily useful only for low level u-boot debugging on tablets, where normal UART0 is difficult to access and requires device disassembly and/or soldering. This patch now allows it to be selected from menuconfig. A dependency on SPL_FEL is added because u-boot does not support booting from NAND yet and also booting from SD card is impossible when a MicroSD breakout board is plugged into the SD slot. Additionally a compilation problem is fixed: common/spl/built-in.o: In function `spl_mmc_load_image': /tmp/u-boot-sunxi/common/spl/spl_mmc.c:94: undefined reference to `mmc_initialize' /tmp/u-boot-sunxi/common/spl/spl_mmc.c:96: undefined reference to `find_mmc_device' /tmp/u-boot-sunxi/common/spl/spl_mmc.c:104: undefined reference to `mmc_init' scripts/Makefile.spl:206: recipe for target 'spl/u-boot-spl' failed Signed-off-by: Siarhei Siamashka <siarhei.siamashka@gmail.com> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk.

2014-08-28scripts: refetch scripts/setlocalversion from Linux 3.16Masahiro Yamada
Now we have CONFIG_LOCALVERSION and CONFIG_LOCALVERSION_AUTO in Kconfig so we can use scripts/setlocalversion without any adjustment. Copy it from Linux 3.16 as is. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
2014-08-22kconfig: convert Kconfig helper script into a shell scriptMasahiro Yamada
Commit 51148790 added scripts/multiconfig.py written in Python 2 to adjust Kconfig for U-Boot. It has been hard for Python 3 users because Python 2 and Python 3 are not compatible with each other. We are not happy about adding a new host tool dependency (in this case, Python version dependency) for the core build process. After some discussion, we decided to use only basic tools. The script may get a bit more unreadable by shell scripting, but we believe it is worthwhile. In addition, this commit revives "<board>_config" target that is equivalent to "<board>_defconfig" for backwards compatibility. It is annoying to adjust various projects which use U-Boot.
