-Subject: [meta-zephyr][PATCH] layer.conf: add kirkstone to layer compatible
- lists
-
-Add Kirkstone to the layer compatbility list now that oe-core master
-only support kirkstone.
-
-Many variables were renamed in oe-core, but as none of them are used in
-meta-zephyr this layer can remain compatible with older layers too.
