2014-04-07kconfig: make allnoconfig disable options behind EMBEDDED and EXPERTJosh Triplett
"make allnoconfig" exists to ease testing of minimal configurations. Documentation/SubmitChecklist includes a note to test with allnoconfig. This helps catch missing dependencies on common-but-not-required functionality, which might otherwise go unnoticed. However, allnoconfig still leaves many symbols enabled, because they're hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT. For instance, allnoconfig still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't typically get build-tested with those disabled. To address this, introduce a new Kconfig option "allnoconfig_y", used on symbols which only exist to hide other symbols. Set it on CONFIG_EMBEDDED (which then selects CONFIG_EXPERT). allnoconfig will then disable all the symbols hidden behind those.

2009-11-15kconfig: Mark various internal functions staticJosh Triplett
kconfig's keyword hash, lexer, and parser define various functions used only locally. Declare these functions as static, and regenerate the corresponding generated files. Signed-off-by: Josh Triplett <josh@joshtriplett.org>
2008-01-28kconfig: remove "enable"Adrian Bunk
Kconfig had a synonym "enable" for "select" that was neither documented nor used. Signed-off-by: Adrian Bunk <bunk@kernel.org> Cc: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2008-01-28kconfig: environment symbol supportRoman Zippel
Add the possibility to import a value from the environment into kconfig via the option syntax. Beside flexibility this has the advantage providing proper dependencies. Documented the options syntax. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-10-12kconfig: syntax cleanup - drop support for "depends/requires/def_boolean"Adrian Bunk
Remove the following redundant and never or rarely used kconfig syntax: - "def_boolean" (same as "def_bool") - "requires" (same as "depends on") - "depends" (same as "depends on") This patch contains the code changes and Kconfig updates. The shipped files are in next patch to let actual codechange stand out.

2006-06-09kconfig: add symbol option config syntaxRoman Zippel
This adds the general framework to the parser to define options for config symbols with a syntax like: config FOO option bar[="arg"] Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2005-11-09[PATCH] kconfig: simplify symbol type parsingRoman Zippel
This simplifies the parser a bit by merging the various symbol types into a single token and adds the type to the keyword hash.

2005-11-09[PATCH] kconfig: use gperf for kconfig keywordsRoman Zippel
Use gperf to generate a hash for the kconfig keywords. This greatly reduces the size of the generated scanner and makes it easier to extend kconfig.
