[U-Boot] U-Boot Security

Hello everyone,

I want to add some supplementary security to my embedded system. The Flattened Image Tree (FIT) to secure the operating system and the device tree, I have already found. Now, I am wondering if I could also secure U-Boot itself before starting it by the Secondary Program Loader (SPL). Does anyone knows a method to do that?

For a helpful answer I would be really grateful.

Sincerely,
