Verifying images in HAB in Linux or OPTEE

Hi, I'm trying to work on an update procedure on an IMX6UL that checks to see if an image will pass the HAB check before updating the images. I'm having trouble accessing the boot ROM from OPTEE so I need to re-implement the authentication function in as a TA in OPTEE or failing that as a regular Linux application, similar to the uboot command hab_auth_img. Is there any code available for this? Is there a way to make the CST do this?
