This adds support for the Kontron i.MX8MP OSM-S size system-on-module +
eval board.
CPU: NXP i.MX8MP @ 1600MHz (quad-core A53)
Memory: 4 (up to 8) GByte LPDDR4-RAM
Storage: 32 (up to 128) GByte eMMC + microSD slot
Ethernet: 2x 1 Gbit/s IEEE (1x with TSN)
UART: 1x UART console output on the Mini-B USB Debug Port
(signals are really UART on this Mini-B USB port!!!, there is
an adapter with ftdi available from Kontron)
1x RS232, 1x RS485
USB: 2x USB 2.0 Type-A, 1x USB 3.0 Type-C DRP
Misc: 8 (up to 128) kByte EEPROM (at24), RTC, 2x CAN, HDMI, 1x PCIe
This will create an SD card image for the board.
To use this image you have to bring the board to the recovery boot mode
(normal boot mode is eMMC). At the time of writing, the SoM (or the SoC)
has a bug that the FORCE_RECOVERY signal (switch S1 on the eval board)
doesn't work as long as the eMMC boot0 partition contains data.
Therefore you have to wipe this boot0 partition to be able to boot from
SD card. To do this call the following commands at uboot:
mmc dev 0 1
mmc erase 0 0x2000
After that, the system will try to boot from SD card.

The KSZ9477 driver was added to the cortexa53 kernel to support the
Gateworks Venice product family which has a board with this switch. Now
that the kmod-dsa-ksz9477 driver is available as a package remove the
static configuration ad add the package.
This resolves an issue caused by having the switch driver static and the
PHY driver as a module such that the PHY driver was not registered early
enough to be used causing some errata to not be worked around.

Enable DT overlay support:
- add dt-overlay to board features
- add DEVICE_DTS_OVERLAYS
- update the boot script to resize before applying each overlay

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

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
