Why not FIT?
Actually before we implement secure boot, we use FIT image, however i.MX8 only support i.MX container format image for secure boot, The chip will verify the container image when secure boot. It could not recognize FIT image. So we have to drop FIT image.
support to let SPL could load container images.
What is a container image? Can you please point to documentation?
Sadly, there is no public reference manual. There is a doc that has a bit of information. https://community.nxp.com/docs/DOC-343178
Thanks, Peng.
