+# linux-yocto-custom.bb:
+#
+#   A yocto-bsp-generated kernel recipe that uses the linux-yocto and
+#   oe-core kernel classes to apply a subset of yocto kernel
+#   management to git managed kernel repositories.
+#
+# Warning:
+#
+#   Building this kernel without providing a defconfig or BSP
+#   configuration will result in build or boot errors. This is not a
+#   bug.
+#
+# Notes:
+#
+#   patches: patches can be merged into to the source git tree itself,
+#            added via the SRC_URI, or controlled via a BSP
+#            configuration.
