From 8bc8be4d0ecd2c939a36f2846ef85d6f469180eb Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Fri, 30 Sep 2016 15:56:27 -0600 Subject: util/lint/kconfig_lint: change warning levels and text - Add an exception for MAINBOARD_POWER_ON_AFTER_POWER_FAIL when checking - With those exceptions set, we don't have anymore #define or #ifdef warnings, so turn them to errors so no more can be pushed. - Change the definition of an unused symbol from a warning to a note. There are times when unused symbols are expected. - Upgrade the warning for loading Kconfig files multiple times from a warning to an error.
