From 44165e4c676d266f73fda2e6ba82b4bf3262daf2 Mon Sep 17 00:00:00 2001
From: Fabien Parent <fparent@baylibre.com>
Date: Fri, 16 Oct 2020 19:52:37 +0200
Subject: [PATCH] tools: mtk_image: add support for booting ARM64 images
mkimage is only able to package aarch32 binaries. Add support for
AArch64 images.
One can create a ARM64 image using the following command line:
mkimage -T mtk_image -a 0x201000 -e 0x201000 -n "media=emmc;arm64=1"
-d bl2.bin bl2.img
