From bfedb4e85a84e817dbe5d8694b8f8fcdd6f2f22a Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Thu, 26 Jul 2018 16:24:21 +0200 Subject: utils: add optional callback to edit_bblayers_conf() Add a callback that lets you modify or remove items in addition to the current scheme where you can only add or remove. This enables you to for example replace a layer with a temporary copy (which is what we will use this for first in OE's oe-selftest).
