I have an i.MX8MM device with secure boot enabled. Is there a secure way to store encrypted data in the Linux world, that can then be read from U-boot? Using a fully encrypted filesystem is not an option.
I was considering using the "blob enc/dec" commands, but I was unable to find clear and up to date instructions on how to use them. Is it even possible to encrypt generic data in Linux, and then decrypt it in U-Boot?

We don't have such a reference implementation yet. After blob decryption, the generated black key is injected into the Linux keyring.
You may have a try to port the decryption blob descriptor to uboot.
