From ee71422b9893f9f77173fb2612d1ffbbc68643c3 Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Fri, 13 Apr 2012 16:55:44 -0400 Subject: linux-yocto: allow .cfg, .scc, .patch and defconfigs to be processed in order During testing/extension of the linux-yocto-tiny kernel it was found that defconfigs were not always properly applied. This was due to two issues: - not being able to fully control the order of objects applied to the git tree on the SRC_URI - defconfigs triggering --allnoconfig before being applied To fix this, the recipe space code that previously detected and generated automatic features moves back to the kernel tools (where it was before) and is updated to also process .cfg and defconfigs. Moving this back to the tools allow other recipes to automatically benefit from the additional support. The second issue is addressed by allowing configme to take --alldefconfig when a recipe wishes to pass a defconfig and override the default behaviour.
