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.

Sadly, there is no public reference manual. There is a doc that has
