From bb96a08d5b48f0ee3415619c2119d7153de1d0c2 Mon Sep 17 00:00:00 2001 From: Bryan O'Donoghue Date: Tue, 24 Apr 2018 18:46:47 +0100 Subject: [PATCH] warp7: Add support for automated secure boot.scr verification This patch adds support for verifying a signed boot.scr. With this in place it's possible for run-time Linux to update boot.scr to set different variables such as switching between different boot partitions, pointing to different kernels etc and for u-boot to verify these changes via the HAB prior to executing the commands contained in boot.scr.
