# short-description: Create SD card image with a boot partition for i.MX8M
# long-description:
# Create an image that can be written onto a SD card using dd for use
# with i.MX8M SoC family
# It uses binary boot container called flash.bin provided directly by
# the U-Boot recipe, and U-Boot ITB files which is created by binman utility
# of U-Boot.
# Those files are added it into the boot partition, which is populated as a
# raw copy into the image.
# Boot container prepared by U-Boot already container SPL, U-Boot itself,
# U-Boot DTB file, ATF, and optional OP-TEE components.
#
# The disk layout used is:
# - ----------- -------------- ----------------------------
# | | flash.bin | u-boot.itb | boot | rootfs |
# - ----------- -------------- ----------------------------
# ^ ^ ^ ^ ^ ^
# | | | | | |
# 0 | 384KiB 8MiB 72MiB 72MiB + rootfs + IMAGE_EXTRA_SPACE (default 10MiB)
# ${IMX_BOOT_SEEK} 32 or 33kiB, see reference manual
