2015-08-19kconfig: warn of unhandled characters in Kconfig commandsAndreas Ruprecht
In Kconfig, definitions of options take the following form: "<COMMAND> <PARAM> <PARAM> ...". COMMANDs and PARAMs are treated slightly different by the underlying parser. While commit 2e0d737fc76f ("kconfig: don't silently ignore unhandled characters") introduced a warning for unsupported characters around PARAMs, it does not cover situations where a COMMAND has additional characters before it. This change makes Kconfig emit a warning if superfluous characters are found before COMMANDs. As the 'help' statement sometimes is written as '---help---', the '-' character would now also be regarded as unhandled and generate a warning. To avoid that, '-' is added to the list of allowed characters, and the token '---help---' is included in the zconf.gperf file.

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.

2010-11-22kconfig: add an option to determine a menu's visibilityArnaud Lacombe
This option is aimed to add the possibility to control a menu's visibility without adding dependency to the expression to all the submenu.

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.

This simplifies the parser a bit by merging the various symbol types into a single token and adds the type to the keyword hash.
