How does U-Boot (SSBL) authenticate next stage boot images?

The current GSRD U-Boot does not feature image authentication beyond the second stage bootloader (U-Boot). You can enable U-Boot to authenticate subsequent boot images (Linux*) by configuring or adding authentication capability to U-Boot. Reference the latest U-Boot releases for support on authentication. You may also want to add specific third-party or open source solutions.
