[U-Boot] [PATCH 1/3] tools: add i.MX8/8X image support
Peng Fan
peng.fan at nxp.com
Tue Oct 16 04:50:30 UTC 2018
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.

Note:
This is a porting from imx-mkimage to U-Boot mkimage for i.MX8/8X.
The README file is not included, this will be added later.
To test this patchset, need apply https://lists.denx.de/pipermail/u-boot/2018-September/341920.html
