Hi Fabio, I really appreciate your response.
I've decided to try to move over to u-boot 2017.07. I saw a bootlin talk(https://bit.ly/2HxxxfK) where they seem to indicate that they had experienced issues with verified boot prior to this version, So I guess I'll just bite the bullet and hope for the best. Thank you for your time.
