From 97e986030ef33dbc43f8e18f7721b98ee381e29b Mon Sep 17 00:00:00 2001 From: Usama Arif Date: Wed, 29 Jul 2020 15:41:18 +0100 Subject: oeqa/selftest/imagefeatures: Add testcase for fitImage This testcase generates the Image Tree Source and the corresponding fitImage containing a kernel and a ramdisk. It then checks if the these files exist and if the right fields are present in the right order in the Image Tree Source.
