Hi in my case I have a machine for each board and I choose the right device-tree at "machine".conf. So MACHINE can be determined by the device tree Im running.
Other option would be echoing the machine to /etc/issue of the image. I do this with DISTRO_VERSION. You can use ROOTFS_POSTPROCESS_COMMAND to achieve this.
