Extract the config files related stuff from the kconfig stuff
- create config/config.mk, with all the config.gen/ rules - the only common points between config files and configurators: - the top-level config file to include, stored in KCONFIG_TOP - the config_file rules, which makes config files available to configurators - dependency-files are renamed from %.d to %.dep (.d is reserved for directories) - a few eye-candy here and there /trunk/kconfig/kconfig.mk | 184 12 172 0 +++-------------------------------------------------- /trunk/config/config.mk | 118 9 109 0 +++------------------------------- /trunk/ct-ng.in | 1 1 0 0 + 3 files changed, 22 insertions(+), 281 deletions(-)
