[PATCH 07/10] MAKEALL: support Kconfig fragments

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add the ability to add kconfig fragments before building a defconfig.
The fragments can be added by either the -k option or by setting
the KCONFIG_ADD envrionment variable to a list of filenames.
