Signing DTB in Secure Boot Implementation

[meetalipatel]

Hello NXP Team,

Greetings!

I am working on Secure Boot Implementation for a custom board based on i.MX8MQ processor. I have signed the imx-boot and Linux kernel image and it is working fine. Now, I would like to sign the Linux kernel DTB. Is there any document mentioning the process for DTB signing, as we have for u-boot and kernel?

Thanks in advance.

Regards

Hello,

There is no document for this since the dtb only describes the hardware and does not store any confidential data. That is the reason why the available documents only focus on u-boot and kernel.
