For targets in U-Boot which were migrated to DM, the correct binary
image filename will be 'u-boot-dtb.img'. For backward compatibility,
keep support for both files and use the one which was generated with
our 'uboot-imx' package.
See also 'CONFIG_SPL_FS_LOAD_PAYLOAD_NAME' and 'CONFIG_OF_CONTROL' in
mainline U-Boot sources.

Modern NXP i.MX series includes several different families, based on
single- or multi-core Arm Cortex-A CPUs. To be able to support more
families within a single target, we split the 'imx' in arch-specific
subtargets, starting with 'cortexa9' for the Cortex-A9 based i.MX 6,
already supported by the original 'imx6' target.
