fixdep: fix dependency on options surrounded by CONFIG_VAL()

2017-10-16T13:42:51Z

CONFIG options surrounded by CONFIG_IS_ENABLED(...) CONFIG_IS_BUILTIN(...) CONFIG_IS_MODULE(...) CONFIG_VAL(...) need special care for proper dependency tracking. I do not remember why, but I missed to add CONFIG_VAL(...) handling. Signed-off-by: Masahiro Yamada

kbuild: fixdep: Check fstat(2) return value

2016-05-23T15:50:21Z

Coverity has recently added a check that will find when we don't check the return code from fstat(2). Copy/paste the checking logic that print_deps() has with an appropriate re-wording of the perror() message.

kbuild: fixdep: drop meaningless hash table initialization

2015-09-15T19:05:23Z

The clear_config() is called just once at the beginning of this program, but the global variable hashtab[] is already zero-filled at the start-up. [ Linux commit: d179e22762fd38414c4108acedd5feca4cf7e0d8 ] Signed-off-by: Masahiro Yamada Signed-off-by: Michal Marek

linux/kconfig.h: add CPP macros useful for per-image config options

2015-08-18T17:46:00Z

The previous commit introduced a useful macro used in makefiles, in order to reference to different variables (CONFIG_... or CONFIG_SPL_...) depending on the build context. Per-image config option control is a PITA in C sources, too. Here are some macros useful in C/CPP expressions. CONFIG_IS_ENABLED(FOO) can be used as a shorthand for (!defined(CONFIG_SPL_BUILD) && defined(CONFIG_FOO)) || \ (defined(CONFIG_SPL_BUILD) && defined(CONFIG_SPL_FOO)) For example, it is useful to describe C code as follows, #if CONFIG_IS_ENABLED(OF_CONTROL) (device tree code) #else (board file code) #endif The ifdef conditional above is switched by CONFIG_OF_CONTROL during the U-Boot proper building (CONFIG_SPL_BUILD is not defined), and by CONFIG_SPL_OF_CONTROL during SPL building (CONFIG_SPL_BUILD is defined). The macro can be used in C context as well, so you can also write the equivalent code as follows: if (CONFIG_IS_ENABLED(OF_CONTROL)) { (device tree code) } else { (board file code) } Another useful macro is CONFIG_VALUE(). CONFIG_VALUE(FOO) is expanded into CONFIG_FOO if CONFIG_SPL_BUILD is undefined, and into CONFIG_SPL_FOO if CONFIG_SPL_BUILD is defined. You can write as follows: text_base = CONFIG_VALUE(TEXT_BASE); instead of: #ifdef CONFIG_SPL_BUILD text_base = CONFIG_SPL_TEXT_BASE; #else text_base = CONFIG_TEXT_BASE; #endif This commit also adds slight hacking on fixdep so that it can output a correct list of fixed dependencies. If the fixdep finds CONFIG_IS_ENABLED(FOO) in a source file, we want $(wildcard include/config/foo.h) in the U-boot proper building context, while we want $(wildcard include/config/spl/foo.h) in the SPL build context.

If the target string matches "CONFIG_", move the pointer p forward. This saves several 7-chars adjustments. Signed-off-by: Masahiro Yamada Reviewed-by: Tom Rini Reviewed-by: Simon Glass

fixdep: remove multiple .config support code

2015-03-06T01:50:30Z

Since commit e02ee2548afe (kconfig: switch to single .config configuration), the ".*.cmd" files are not correctly created for SPL/TPL. The U-Boot extension code in fixdep, which was introduced to support the multiple .config, must be removed. Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass

kconfig: switch to Kconfig

2014-07-30T12:48:03Z

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 _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: / Here, is either 'spl' or 'tpl' is 'config', 'menuconfig', 'xconfig', etc. When the configuration is done, run "make". (Or "make _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. Signed-off-by: Masahiro Yamada Acked-by: Simon Glass
