From 3939a216a53f58831e640e85ed95f7edff3ca76f Mon Sep 17 00:00:00 2001 From: Joshua Lock Date: Tue, 4 Jan 2011 20:28:20 +0000 Subject: bitbake: implement command to find configuration files for a config variable Some configuration variables (MACHINE, MACHINE-SDK and DISTRO) set which confguration files bitbake should use. The added command , findConfigFiles, enables a UI to query which files are suitable values for a specified parameter.
