From a2b96ece5be146f4995d737f047e5bbb76079b8f Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Tue, 16 Oct 2018 04:50:30 +0000 Subject: [PATCH] tools: add i.MX8/8X image support i.MX8/8X bootable image type is container type. The bootable image, containers a container set which supports two container. The 1st container is for SECO firmware, the 2nd container needs to include scfw, m4_0/1 image, ACore images per your requirement.
