kconfig: fix select in combination with default

You've hit the rather subtle rules of select vs default. What happened is that SERIO is selected to m, but SERIO_I8042 isn't selected so the default of y is used instead. We already had the problem in the past that select and default don't work well together, so this patch cleans this up and makes the rule hopefully more straightforward. Basically now the value is calculated like this: (value && dependency) || select where the value is the user choice (if available and the symbol is visible) or default. In this case it means SERIO and SERIO_I8042 are both set to y due to their default and if SERIO didn't had the default, then the SERIO_I8042 value would be limited to m due to the dependency. I tested this patch with more 10000 random configs and above case is the only the difference that showed up, so I hope there is nothing that depended on the old more complex and subtle rules.

kconfig: ignore select of unknown symbol

2008-02-03T07:58:07Z

We have had warnings for a long time about select of unknow symbol but the warnings does not really makes sense since we may select a symbol that is relevant and defined in one arch but not in another arch. And as long as we do not use a common set of Kconfig files for all archs lets just ignore this case. Previously we have used this to find bad uses of select but we need a more relaible method to do so. Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: mark config as changed when loading an alternate config

Michal Zachar reported that menuconfig did not save the new config when loading an alternate config unless he altered it manually. Mark config as changed upon load of alternate config fixed this. Signed-off-by: Sam Ravnborg Roman Zippel

kconfig: tristate choices with mixed tristate and boolean values

2008-01-28T22:21:18Z

Change kconfig behavior so that mixing bool and tristate config settings in a choice is possible and has the desired effect of offering just the tristate options individually if the choice gets set to M, and a normal boolean selection if the choice gets set to Y. Also fix scripts/kconfig/conf's handling of children of choice values - there may be more than one immediate child, and all of them need to be processed.

kconfig: environment symbol support

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
