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?
Just as U-Boot can load Kernel + DTS as FIT, SPL can load U-Boot as FIT.
See CONFIG_SPL_LOAD_FIT. This FIT containing U-Boot + its DTS can then
be verified, too.
Regards,
Simon
