was submitted for revision and it takes some time to become part of a stable \
version, or because it is not applicable for upstreaming."

#
# imx8m machines require additional deployment tasks to be
# carried out due to the fact that final boot image is constructed
# using imx-boot recipe. It produces a boot binary image, which is
# constructed from various binary components (u-boot with separate
# dtb, atf, DDR firmware and optional op-tee) into a single image
# using FIT format. This image is then parsed and loaded either via
# SPL directly (imx8mm), or using bootrom code (imx8mn and imx8mp).
#
# In order for imx-boot to construct the final binary boot image,
# it is required that the U-Boot dtb files are to be deployed into
# a location known by imx-boot so they could be picked up and
# inserted into the boot container.
#
# NOTE: This is only applicable to those derivatives of mx8m family,
# which did not adopt the boot container mechanism provided by U-Boot
# build system itself. U-Boot is capable of producing a result binary,
# which includes all those deployed pieces below, hence once derivative
# starts to use it - below append would not be necessary.
# Once all mx8m derivatives are migrated to use the 'flash.bin' boot
# container - this append can be dropped completely.
