imx: imx-common: add elf firmware support
Support elf firmware files for the auxiliary Cortex-M4 core. This
has the advantage that the user does not need to know to which
address the binary has been linked to. However, in order to load
the elf sections to the right address, we need to translate the
Cortex-M4 core memory addresses to primary/host CPU memory
addresses (U-Boot is typically running on the A7/A9 core). This
allows to boot firmwares from any location with just using
bootaux, e.g.:
tftp ${loadaddr} low_power_demo.elf && bootaux ${loadaddr}
