commit ae8bf1a26e15f89d17deca031253c3261b3a6c36
Author: Tim Harvey <tharvey at gateworks.com>

    imx: add imx8m support
    
    Add imx8m support:
     - add a cortexa53 subtarget to imx
     - move ARCH and KERNELNAME to subtargets
     - account for kernel modules that are not used for cortexa53
    
    No device-specific targets or firmware images are created yet but all
    imx8m* dtbs will be built.
    
    enabling CONFIG_TARGET_ROOTFS_INITRAMFS results in
    openwrt-imx-cortexa53-imx8m-initramfs-kernel.bin which has been
    successfully booted on an imx8mm-evk using the following:
    
    u-boot=> tftpboot $fdt_addr_r image-imx8mm-evk.dtb && \
    tftpboot $kernel_addr_r openwrt-imx-cortexa53-imx8m-initramfs-kernel.bin && \
    booti $kernel_addr_r - $fdt_addr_r
