imx: add Gateworks Venice support Add support for Gateworks Venice imx8m family of boards: - required kernel modules for on-board devices - image generation - initial network config - sysupgrade support The resulting compressed disk image (bin/targets/imx/cortexa53/openwrt-imx-cortexa53-gateworks_venice-squashfs-img.gz) can be installed on a Gateworks venice board via U-Boot: u-boot=> tftpboot $loadaddr openwrt-imx-cortexa53-gateworks_venice-squashfs-img.gz && \ gzwrite mmc $dev $loadaddr $filesize WARNING: this will overwrite any boot firmware on the eMMC user hardware partition which if being used will brick your board requiring JTAG to re-program boot firmware and recover The compressed disk image contains the partition table and filesystems only and that it is expected that boot firmware is installed properly on the eMMC boot0 hardware partition. The easiest way to ensure this is to use the Gateworks JTAG adapter/process to install the latest boot firmware as follows from a Linux host: wget http://dev.gateworks.com/jtag/jtag_usbv4 chmod +x jtag_usbv4 wget http://dev.gateworks.com/venice/images/firmware-venice-imx8mm.bin sudo ./jtag_usbv4 -p firmware-venice-imx8mm.bin Signed-off-by: Tim Harvey <tharvey@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 Signed-off-by: Tim Harvey <tharvey@gateworks.com>
