Vendor Authorized Boot is a security feature for authenticating the images such as U-Boot, ARM trusted Firmware, Linux kernel, device tree blob and etc loaded from FIT. After those images are loaded from FIT, the VAB certificate and signature block appended at the end of each image are sent to Secure Device Manager (SDM) for authentication. U-Boot will validate the SHA384 of the image against the SHA384 hash stored in the VAB certificate before sending the image to SDM for authentication.
