I want to implement Secure Boot & OPTEE on FRDM i.MX 91 Development Board. So far I have generated Private & Public Keys by following - https://wiki.amarulasolutions.com/opensource/uboot/secure_boot/imx8mm_habv4.html and using IMX_CST_TOOL_NEW. Need reference documents and guidance to implement the Secure Boot & OPTEE on my iMX91 FRDM board with Yocto enviromment. Also, I am new to Yocto Environement, so additional hints would help.
