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

kconfig: switch to single .config configuration 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.

kconfig: switch to Kconfig This commit enables Kconfig. Going forward, we use Kconfig for the board configuration. mkconfig will never be used. Nor will include/config.mk be generated. Kconfig must be adjusted for U-Boot because our situation is a little more complicated than Linux Kernel. We have to generate multiple boot images (Normal, SPL, TPL) from one source tree. Each image needs its own configuration input. Usage: Run "make <board>_defconfig" to do the board configuration. It will create the .config file and additionally spl/.config, tpl/.config if SPL, TPL is enabled, respectively. You can use "make config", "make menuconfig" etc. to create a new .config or modify the existing one. Use "make spl/config", "make spl/menuconfig" etc. for spl/.config and do likewise for tpl/.config file. The generic syntax of configuration targets for SPL, TPL is: <target_image>/<config_command> Here, <target_image> is either 'spl' or 'tpl' <config_command> is 'config', 'menuconfig', 'xconfig', etc. When the configuration is done, run "make". (Or "make <board>_defconfig all" will do the configuration and build in one time.) For futher information of how Kconfig works in U-Boot, please read the comment block of scripts/multiconfig.py. By the way, there is another item worth remarking here: coexistence of Kconfig and board herder files. Prior to Kconfig, we used C headers to define a set of configs. We expect a very long term to migrate from C headers to Kconfig. Two different infractructure must coexist in the interim. In our former configuration scheme, include/autoconf.mk was generated for use in makefiles. It is still generated under include/, spl/include/, tpl/include/ directory for the Normal, SPL, TPL image, respectively.

TPL : introduce the TPL based on the SPL Due to the nand SPL on some board(e.g. P1022DS)has a size limit, it can not be more than 4K. So, the SPL cannot initialize the DDR with the SPD code. This patch introduces TPL to enable a loader stub that is loaded by the code from the SPL. It initializes the DDR with the SPD or other operations. The TPL's size is sizeable, the maximum size is decided by the memory's size that TPL runs. It initializes the DDR through SPD code, and copys final uboot image to DDR. So there are three stage uboot images: * spl_boot, * tpl_boot, * final uboot image Signed-off-by: Ying Zhang <b40530@freescale.com> Acked-by: York Sun <yorksun@freescale.com>

kbuild: improve Kbuild speed Kbuild brought about many advantages for us but a significant performance regression was reported by Simon Glass. After some discussions and analysis, it turned out its main cause is in $(call cc-option,...). Historically, U-Boot parses all config.mk (arch/*/config.mk and board/*/config.mk) every time descending into subdirectories. That means cc-options are evaluated over and over again. $(call cc-option,...) is useful but costly. So we want to evaluate them only in ./Makefile and spl/Makefile and export compiler flags. This commit changes the build system as follows: - Modify scripts/Makefile.build to not include config.mk Instead, add $(PLATFORM_CPPFLAGS) to asflags-y, ccflags-y, cppflags-y. - Export many variables Going forward, Kbuild will not parse config.mk files when it descends into subdirectories. If we want to set variables in config.mk and use them in subdirectories, they must be exported.

spl: Add support for CONFIG_OF_EMBED=y CONFIG_OF_EMBED=y is the option which is here only for testing purpose and shouldn't be enabled by default as is describe at: "dts: Add a comment about CONFIG_OF_EMBED being for local use" (sha1: 3d3f60cb7a6bb6c338e00a9769fa918a8536096c) But still enabling this option locally shouldn't end up with compilation error when you build SPL. This patch fix it.

# Add GCC lib
kbuild: add CONFIG_ prefix to USE_PRIVATE_LIBGCC Before this commit, USE_PRIVATE_LIBGCC was defined in arch-specific config.mk and referenced in arch/$(ARCH)/lib/Makefile. We are not happy about parsing config.mk again and again. We have to keep the same behavior with a different way. By adding "CONFIG_" prefix, this macro appears in include/autoconf.mk, include/spl-autoconf.mk. (And treating USE_PRIVATE_LIBGCC as CONFIG macro is reasonable enough.) Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes" in arch/arm/cpu/arm720t/tegra*/config.mk, whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk. It means Tegra enables PRIVATE_LIBGCC only for SPL. We can describe the same behavior by adding #ifdef CONFIG_SPL_BUILD # define CONFIG_USE_PRIVATE_LIBGCC #endif to include/configs/tegra-common.h.

The include/autoconf.mk is generated like follows: [1] Preprocess include/common.h with -DDO_DEPS_ONLY and retrieve macros into include/autoconf.mk.tmp [2] Reformat include/autoconf.mk.dep into include/autoconf.mk with tools/scripts/define2mk.sed script [3] Remove include/autoconf.mk.tmp Here, include/autoconf.mk.tmp is similar to u-boot.cfg, which is also generated by preprocessing include/config.h with -DDO_DEPS_ONLY. In other words, there is much overlap among include/autoconf.mk and u-boot.cfg build rules. So, the idea is to split the build rule of include/autoconf.mk into two stages. The first preprocesses headers into u-boot.cfg. The second parses the u-boot.cfg into include/autoconf.mk. The build rules of u-boot.cfg in Makefile and spl/Makefile will be gone.

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

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

Makefile: Fix linking with modern binutils Since Binutils 1a9ccd70f9a7[1] u-boot will not link targets that set CONFIG_SYS_TEXT_BASE=0 with the following error: LD u-boot arm-linux-gnueabi-ld.bfd: u-boot: Not enough room for program headers, try linking with -N arm-linux-gnueabi-ld.bfd: final link failed: Bad value The issue can be reproduced with the bad binutils and the rock2_defconfig target. This issue was also encountered by the powerpc kernel[2], with the fix being to pass --no-dynamic-linker for linkers newer than 2.26 when this flag was introduced. The option tells ld that the PIE or shared lib does not need loaded program headers. Ubuntu Zesty's Binutils 2.27.51.20161202 hits this error.

Makefile: Add target for building bootable SPL image for SoCFPGA Add build target for generating boot partition images recognised by the SoCFPGA BootROM. The SoCFPGA BootROM expects four copies of the u-boot-spl-dtb.sfp at the beginning of boot partition. Those are u-boot-spl-dtb.bin augmented by a header with which the BootROM can work. The u-boot-dtb.img uImage is appended to this to produce a full boot partition image, the u-boot-with-spl-dtb.sfp . This is the name of the final target. Signed-off-by: Marek Vasut <marex@denx.de>

sunxi: Store the device tree name in the SPL header This patch updates the mksunxiboot tool to optionally add the default device tree name string to the SPL header. This information can be used by the firmware upgrade tools to protect users from harming themselves by trying to upgrade to an incompatible bootloader. The primary use case here is a non-removable bootable media (such as NAND, eMMC or SPI flash), which already may have a properly working, but a little bit outdated bootloader installed. For example, the user may download or build a new U-Boot image for "Cubieboard", and then attemept to install it on a "Cubieboard2" hardware by mistake as a replacement for the already existing bootloader. If this happens, the flash programming tool can identify this problem and warn the user. The size of the SPL header is also increased from 64 bytes to 96 bytes to provide enough space for the device tree name string.
