From 9e307d2887ebdef5e9624d013ae300d29610f69f Mon Sep 17 00:00:00 2001 From: Max Krummenacher Date: Sun, 2 Feb 2020 12:38:08 +0100 Subject: local.conf: sync with oe-core sample The 'Parallelism Options' are now set in bitbake.conf to a sensible default. Some options are now set with ?= to allow for easier overrides. A lot of trailing whitspace has been removed.
