kconfig: environment symbol support

2008-01-28T22:14:39Z

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 Signed-off-by: Sam Ravnborg

kconfig: explicitly introduce expression list

2008-01-28T22:14:39Z

Rename E_CHOICE to E_LIST to explicitly add support for expression lists. Add a helper macro expr_list_for_each_sym to more easily iterate over the list. Signed-off-by: Roman Zippel Signed-off-by: Sam Ravnborg

kconfig: delete unused FILE_ and SYMBOL_ flags

2008-01-28T22:14:38Z

The *_PRINTED flags were never used - so delete them. Do we need them later then we can re-add them. Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: rename E_OR & friends to avoid name clash

2008-01-28T22:14:38Z

We had macros named the same as a set of enumeration values. It is legal code but very confusing to read - so rename the macros from E_* to EXPR_* Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: remove unused members from struct symbol

2007-07-25T19:14:30Z

dep and dep2 in struct symbol was unused - remove them. Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: attach help text to menus

This patch does this and at the same time introduce a few API funtions used to access the help text. The relevant api functions are introduced in the various frontends.

kconfig: add defconfig_list/module option

2006-06-09T05:31:30Z

This makes it possible to change two options which were hardcoded sofar. 1. Any symbol can now take the role of CONFIG_MODULES 2. The more useful option is to change the list of default file names, which kconfig uses to load the base configuration if .config isn't available.

kconfig: integrate split config into silentoldconfig

2006-06-09T05:31:30Z

Now that kconfig can load multiple configurations, it becomes simple to integrate the split config step, by simply comparing the new .config file with the old auto.conf (and then saving the new auto.conf). A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).

kconfig: allow loading multiple configurations

2006-06-09T05:31:30Z

Extend conf_read_simple() so it can load multiple configurations. Signed-off-by: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg

kconfig: allow multiple default values per symbol

2006-06-09T05:31:30Z

Extend struct symbol to allow storing multiple default values, which can be used to hold multiple configurations. Signed-off-by: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Sam Ravnborg
