I am currently using u-boot for iMXRT105x found in: https://github.com/EmcraftSystems/u-boot-fsl
I would like to enable HAB to sign u-boot. But before doing so, I would like to enable the HAB-support feature in u-boot (CONFIG_SECURE_BOOT). Has anybody ported HAB-support feature in u-boot for iMXRT105x target?
From the u-boot source, arch/arm/mach-imx is a good place to start and based the starting point from imx6.
