* kbuild: remove scripts/multiconfig.shMasahiro Yamada2015-03-28-0/+10
| | | | | | | | | | | | 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.

* kconfig: remove unneeded U-Boot extension codeMasahiro Yamada2015-03-02-8/+0
| | | | | | | This code was introduced to support the multiple .config configuration in U-Boot. We do not need it any more. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* kconfig: Fix warning "‘jump’ may be used uninitialized"Peter Kümmel2014-12-08-2/+2
| | | | | | | | | | | | | | | | Warning: In file included from scripts/kconfig/zconf.tab.c:2537:0: scripts/kconfig/menu.c: In function ‘get_symbol_str’: scripts/kconfig/menu.c:590:18: warning: ‘jump’ may be used uninitialized in this function [-Wmaybe-uninitialized] jump->offset = strlen(r->s); Simplifies the test logic because (head && local) means (jump != 0) and makes GCC happy when checking if the jump pointer was initialized.

* kbuild: Make scripts executableMasahiro Yamada2014-11-12-0/+0
| | | | | | | | | | The Makefiles call the respective interpreter explicitly, but this makes it easier to use the scripts manually. (This commit follows commit 06ed5c2bfaca of Linux Kernel) Signed-off-by: Michal Marek <mmarek@suse.cz> Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* kconfig: sync kconfig files with Linux 3.18-rc1Masahiro Yamada2014-11-07-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | This commit imports Kconfig updates from Linux 3.18-rc1. 'kvmconfig' and 'tinyconfig' help message have been commented out since they are unavailable at least now; in the future perhaps we can implement 'tinyconfig' to disable most of CONFIG_CMD_* to create a very small U-Boot image.

* kbuild: improve multi-objs dependency and cleanupsMasahiro Yamada2014-11-07-32/+3
| | | | | | | | | | | | | | | | | | | | | | Since Linux 3.18-rc1, Kbuild is able to handle multi-objs dependency correctly, which also allows us futher cleanups of some makefiles. This commit imports those commits: [1] commit c8589d1e9e01 by Masahiro Yamada kbuild: handle multi-objs dependency appropriately [2] commit 97e3226e6e98 by Masahiro Yamada kbuild: handle the dependency of multi-objs hostprogs appropriately [3] commit 022af62d0190 by Masahiro Yamada kbuild: refactor script/kconfig/Makefile [4] commit 221ecca6cafe by Masahiro Yamada kbuild: remove redundant clean-files from scripts/kconfig/Makefile Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

* kconfig: switch to KconfigMasahiro Yamada2014-07-30-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
