From 76bbf1c634f4a09e1b3e19468738842a2289dc1e Mon Sep 17 00:00:00 2001 From: Sumit Garg Date: Mon, 5 Jun 2017 23:51:51 +0530 Subject: [PATCH] arm64: ls1043ardb: Add distro secure boot support Enable validation of boot.scr script prior to its execution dependent on "secureboot" flag in environment. Disable fall back option to nor/qspi boot in case of secure boot. Also enable "secureboot=y" flag in environment for ARM based platforms instead of bootcmd.
