176b8df701 imx: coretexa53: fix network configuration for GW74xx
The GW74xx's first RJ45 is eth0 which should be the WAN adapter, not
eth1 which is the CPU uplink port to the switch.

bd512e368f 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

ae8bf1a26e 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
