From 82d01f04facef1276cede067efd02d2a731ffe83 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sun, 24 Jan 2021 14:34:12 +0000 Subject: [PATCH] efi_loader: switch to non-secure mode later MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some ARMv7 boards using PSCI require to be in secure-mode when booted via 'bootz' or 'bootm'. During distro-boot 'bootefi bootmgr' is called to check if booting via UEFI is possible. With the change we change the switch from secure mode to non-secure mode is moved from the UEFI subsystem setup to just before calling StartImage().
