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
