+I. Adding the enea-bsp-ppc layer to your build
+=================================================
+
+In order to use this layer, you need to make the build system aware of
+it.
+
+Assuming the enea-bsp-ppc layer exists at the top-level of your
+yocto build tree, you can add it to the build system by adding the
+location of the enea-bsp-ppc layer to bblayers.conf, along with any
+other layers needed. e.g.:
+
+
+  BBLAYERS ?= " \
+      /path/to/yocto/meta \
+      /path/to/yocto/meta-yocto \
+      /path/to/yocto/meta-enea-base \
+      /path/to/yocto/meta-fsl-ppc \
