From deb80ec023ecace8afa3dc13c1bef757a247b206 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Tue, 17 Aug 2021 08:17:18 +0200 Subject: imx: spl: fix imx8m secure boot cherry-picked from NXP code: 719d665a87c6: ("MLK-20467 imx8m: Fix issue for booting signed image through uuu") which fixes secure boot on imx8m based boards. Problem was that FIT header and so IVT header too, was loaded to memallocated address. So the ivt header address coded in IVT itself does not fit with the real position.
