Verify signed images from Linux user space

Hi.

 

I am using the authenticated boot feature of i.MX6ul and I would like to ask:

 

How can I verify a signed image (for example signed Kernel with device tree) from Linux user-space?

 

While doing a firmware upgrade, I would like to verify that the new firmware will successfully boot before flashing it to the memory the device boots from.

 

Regards,

Michal
