2021-09-30kconfig: rename a variable in the lexer to a clearer nameMasahiro Yamada
In Kconfig, like Python, you can enclose a string by double-quotes or single-quotes. So, both "foo" and 'foo' are allowed. The variable, "str", is used to remember whether the string started with a double-quote or a single-quote because open/closing quotation marks must match. The name "str" is too generic to understand the intent. Rename it to "open_quote", which is easier to understand. The type should be 'char'.

2021-09-30kconfig: narrow the scope of variables in the lexerMasahiro Yamada
The variables, "ts" and "i", are used locally in the action of the [ \t]+ pattern in the <HELP> start state. Define them where they are used. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: change "modules" from sub-option to first-level attributeMasahiro Yamada
Now "modules" is the only member of the "option" property. Remove "option", and move "modules" to the top level property. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: remove allnoconfig_y optionMasahiro Yamada
Now that the only user, CONFIG_EMBEDDED has stopped using this option, remove it entirely. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: change defconfig_list option to environment variableMasahiro Yamada
"defconfig_list" is a weird option that defines a static symbol that declares the list of base config files in case the .config does not exist yet. This is quite different from other normal symbols; we just abused the "string" type and the "default" properties to list out the input files. They must be fixed values since these are searched for and loaded in the parse stage. It is an ugly hack, and should not exist in the first place. Providing this feature as an environment variable is a saner approach. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

Fix some warnings from sparce like follows: warning: symbol '...' was not declared. Should it be static? Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2019-05-14kconfig: use snprintf for formatting pathnamesJacob Garber
Valid pathnames will never exceed PATH_MAX, but these file names are unsanitized and can cause buffer overflow if set incorrectly. Use snprintf to avoid this. This was flagged during a Coverity scan of the coreboot project, which also uses kconfig for its build system.
