From 126f2b2853502a7e74e73c11b86a25510a76b9c0 Mon Sep 17 00:00:00 2001 From: Daniel Fandrich Date: Fri, 8 Jul 2011 07:59:16 +0200 Subject: [PATCH] Support configuring Busybox from _defconfig files The existing test .config files are moved to configs/ and renamed to *_defconfig. 'make xyz_defconfig' will enable the configuration in that specific file.
