Hi All,

Can you please share your inputs on how to use the AES crypto for encryption and booting linux, ramdisk and devicetree images. Appreciate if share any document that already did this encryption on u-boot.

For linux and ramdisk this should be easy enough - my verified boot series creates a fit_image_load() function where this feature could be added i think. For device tree it is a little more tricky, since at present we look inside the device trees to determine the compatible string so we know which device tree to pass to Linux. So we would need to decrypt each one before looking at it.

Still overall I don't think this would be hard. Are you trying to hide the binaries so that no one can read them from the flash?

Regards, Simon

Thanks, Jagan.
