   4 Subject: [PATCH] overlays: Fix miniuart-bt "krnbt" parameter
   5
   6 Although superficially appealing, an overlay parameter that targets a
   7 label in the base DTB is not currently supported. Instead it is
   8 necessary to create a fragment targeting the label which is patched
   9 by the parameter.
