* utils/diffconfig: remove BR2_* prefix restrictionMarcel Patzlaff2018-10-211-15/+17
| | | | | | | | | | | | | | | | | | | The utils/diffconfig script works only on variables with the BR2_ prefix. This is OK for Buildroot [def]configs since this is the prefix for all user-facing variables, but it prevents using the same script to compare configs from kconfig-based packages. Remove the BR2_ restriction, allowing usage such as: ./utils/diffconfig \ board/qemu/xtensa-lx60/linux.config \ board/qemu/xtensa-lx60/linux-nommu.config Signed-off-by: Marcel Patzlaff <m.patzlaff@pilz.de> Reviewed-by: Luca Ceresoli <luca@lucaceresoli.net> Tested-by: Luca Ceresoli <luca@lucaceresoli.net> Reviewed-by: Matt Weber <matthew.weber@rockwellcollins.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
* utils/diffconfig: add diffconfig utilityMarcus Folkesson2017-11-251-0/+136
Diffconfig is a simple utility for comparing two configuration files. See usage in the script for more info. Borrowed from the Linux kernel source code and adapted to Buildroot.
