From fd1517e2b51a170f2427122c6b95396db251d827 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Wed, 10 Aug 2022 14:35:29 +0100 Subject: classes: Update classes to match new bitbake class scope functionality Move classes to classes-global or classes-recipe as appropriate to take advantage of new bitbake functionality to check class scope/usage.
