From 432e7619a7bd0c6a2075a618e5b17100fe459085 Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Fri, 14 Jan 2011 00:33:26 -0500 Subject: linux-yocto: streamline new BSP creation By setting BOOTSTRAP to the branch that should be used for a currently undefined BSP a build can be completed and an environment for streamlining the BSP created. With the appropriate machine.conf, and a defconfig any MACHINE can be built against and inherit the configuration of the standard yocto kernel.
