Prepares source files which are sourced from the main Kconfig because upstream kconfiglib doesn't support sourcing
|
||
|
|
a file list. The inputs are the same environment variables which are used by kconfiglib:
|
||
|
|
- COMPONENT_KCONFIGS,
|
||
|
|
- COMPONENT_KCONFIGS_SOURCE_FILE,
|
||
|
|
- COMPONENT_KCONFIGS_PROJBUILD,
|
||
|
|
- COMPONENT_KCONFIGS_PROJBUILD_SOURCE_FILE.
|
||
|
|
|
||
|
|
The outputs are written into files pointed by the value of
|
||
|
|
- COMPONENT_KCONFIGS_SOURCE_FILE,
|
||
|
|
- COMPONENT_KCONFIGS_PROJBUILD_SOURCE_FILE,
|
||
|
|
|
||
|
|
After running this function, COMPONENT_KCONFIGS_SOURCE_FILE and COMPONENT_KCONFIGS_PROJBUILD_SOURCE_FILE will
|
||
|
|
contain a list of source statements based on the content of COMPONENT_KCONFIGS and COMPONENT_KCONFIGS_PROJBUILD,
|
||
|
|
respectively. For example, if COMPONENT_KCONFIGS="var1 var2 var3" and
|
||
|
|
COMPONENT_KCONFIGS_SOURCE_FILE="/path/file.txt" then the content of file /path/file.txt will be:
|
||
|
|
source "var1"
|
||
|
|
source "var2"
|
||
|
|
source "var3"
