From 378f67bd825b4926113fb60588c81b4ffb05b704 Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Tue, 18 Oct 2022 19:21:19 +0100 Subject: externalsrc: move back to classes The externalsrc class was moved to classes-recipe as part of oe-core f5c1280, but it can be used in both recipe and global contexts so move it back to classes/.
