* kconfig: switch to KconfigMasahiro Yamada2014-07-30-62/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9e41403 (kbuild: change out-of-tree build) changed the U-Boot build working directory to the output tree for the out-of-tree builds. This broke the {c,e}tags/cscope build targets as TAG_SUBDIRS variable collected directories based on assumption that the build working directory is the U-Boot source tree directory. Fix the {c,e}tags/cscope build targets by adding the $(srctree) prefix. Also, remove the $(obj) prefix from the etags build target to finish the $(obj) prefix removal started by the same commit.

| | | | | | | | | | | | | | In some cases, an externally-built device tree binary is required to be attached to U-Boot. An example is when using image signing, since in that case the .dtb file must include the public keys. Add a DEV_TREE_BIN option to the Makefile, and update the documentation. Usage is something like: make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb Signed-off-by: Simon Glass <sjg@chromium.org>

If it doesn't, that generally means that some extra sections are being added to u-boot.bin, meaning that it is not possible to access data appended to the U-Boot binary. This is used for device tree, so needs to work. This problem was introduced by commit b02bfc4. By adding a test we can prevent a reccurence. Signed-off-by: Simon Glass <sjg@chromium.org>
* Makefile: fix clang warnings due to clang supportJeroen Hofstee2014-06-11-28/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building u-boot tools with clang as a host compiler e.g. on FreeBSD with `gmake HOSTCC=clang CONFIG_USE_PRIVATE_LIBGCC=y tools` leads to many warnings [1] for every compiler invocation since commit 598e2d33. Part of mentioned commit imports linux patches: - kbuild: LLVMLinux: Adapt warnings for compilation with clang - kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang No version of clang supports the gcc fno-delete-null-pointer-checks though, but it is only passed to clang. Gcc does not have the clang specific Qunused-arguments for the target. Furthermore several warnings are disabled which aren't encountered in u-boot. Since such a build has worked for quite some time and works after removing these changes, just remove the clang specific handling to restore normal building with clang as hostcc. [1] Actual warnings ------------------- GEN include/autoconf.mk.dep arm-freebsd-gcc: unrecognized option '-Qunused-arguments' HOSTCC scripts/basic/fixdep clang: warning: argument unused during compilation: '-fno-delete-null-pointer-checks' cc: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

Here, u-boot.img = uImage header + u-boot.bin To use OF control with a separate devicetree, u-boot.dtb must be placed right after u-boot.bin. In this case, u-boot-dtb.bin is generally used. Here, u-boot-dtb.bin = u-boot.bin + u-boot.dtb We need u-boot-dtb.img to use both SPL framework and separate OF control at the same time. u-boot-dtb.img = uImage header + u-boot-dtb.bin For example, Zynq boards already define all of - CONFIG_SPL - CONFIG_OF_CONTROL - CONFIG_OF_SEPARATE So, the support of u-boot-dtb.img is urgent.

However, CONFIG_SPL_MAX_SIZE is used in the Makefile for padding the SPL when preparing an u-boot.ais image. By removing CONFIG_SPL_MAX_SIZE said commits broke the ais image of the da850evm and cam_enc_4xx configurations. This patch converts the u-boot.ais target to use CONFIG_SPL_PAD_TO instead of CONFIG_SPL_MAX_SIZE for padding the SPL and adds a #define CONFIG_SPL_PAD_TO where it is required.

| * kbuild: create a build directory automatically for out-of-tree buildMasahiro Yamada2014-03-28-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to Kbuild, the build system created a build directory, when it did not exist, for out-of-tree build. This feature was dropped when we switched to Kbuild because many of lines in makefiles were copied from Linux Kernel. (In Linux Kernel, we have to create a build directory by ourselves before starting build.) That feature seems worth reviving for less typing even if our code and Linux Kernel diverge.
