+ CreateBBLayersConf: This build step creates the bblayers.conf used by the
+ build system to determine which layers to use and where to find them.
+
+ {'CreateBBLayersConf': {'buildprovider' : 'yocto',
+ 'bsplayer':'True',
+ 'bspprovider':'intel',
+ 'bbtextprepend':'text_to_prepend',
+ 'bbtextappend':'text_to_append',
+ 'layerdirs': ['layerdir1', 'layerdir2', ...]}}
+
+ buildprovider: Optional and defaults to 'yocto'. If this is set to
+ 'yocto', then it adds the layers' 'meta', 'meta-yocto' and
+ 'meta-yocto-bsp' to BBLAYERS. If set to 'oe', then only 'meta' is
+ added to BBLAYERS.
+
+ bsplayer: Optional and defaults to False. Set this to 'True' if you
+ want to use an established BSP layer and include its default layers.
+
+ bspprovider: Required if bsplayer is set to True. Defines the BSP
+ provider so the default layers can be included. At this time only
+ 'intel', 'fsl-ppc' and 'fsl-arm' are recognized.
+
+ bbtextprepend: Prepends the given text to bblayers.conf. Use \n in
+ the text to start a new line and always end the text with a \n. For
+ example:
+ 'bbtextprepend': '#Adding one comment line\n#Adding a second comment line\n'
+
+ bbtextappend: Appends the given text to bblayers.conf. Same format
+ as bbtextprepend.
+
+ layerdirs: Used to add layers to BBLAYERS. Layers are added in the
+ order specified and are added after the layers created by the
+ buildprovider. For example:
+ 'layerdirs': ['meta-openembedded/meta-oe',
+ 'meta-openembedded/meta-networking',
+ 'meta-openembedded/meta-gnome']
+ will append the layers meta-openembedded/meta-oe,
+ meta-openembedded/meta-networking, and meta-openembedded/meta-gnome
+ to BBLAYERS. Note that this will override any default layers from a
+ bspprovider.
