From 4f1674fc32224003931af4a74aa18168786ec9a2 Mon Sep 17 00:00:00 2001 From: Ulf Magnusson Date: Sat, 27 Apr 2019 14:16:10 +0200 Subject: defconfig: Add script Simple script for initializing the configuration from an existing configuration file (usually a minimal configuration). Just copying the minimal configuration to .config would usually work, due to Kconfig semantics, but having it be a full configuration file from the start might be handier and less confusing. --- defconfig.py | 43 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100755 defconfig.py (limited to 'defconfig.py') diff --git a/defconfig.py b/defconfig.py new file mode 100755 index 0000000..7b02833 --- /dev/null +++ b/defconfig.py @@ -0,0 +1,43 @@ +#!/usr/bin/env python + +# Copyright (c) 2019, Ulf Magnusson +# SPDX-License-Identifier: ISC + +""" +Reads a specified configuration file, then writes a new configuration file. +This can be used to initialize the configuration from e.g. an arch-specific +configuration file.
