patches:
- remove patches from 6.7-6.12 that are now upstream.
- refresh remaining patches
- 502-6.13-arm64-dts-freescale-rename-gw7905-to-gw75xx.patch was
misnamed as that patch went upstream in 6.12 and thus is also removed
- 504-6.13-arm64-dts-imx-Add-i.MX8M-Plus-Gateworks-GW82XX-2X-support.patch
was refreshed to the final version that was accepted upstream
- 600-PCI-imx6-Start-link-at-max-gen-first-for-IMX8MM-and-IMX8MP.patch
was removed while I investigate an upstream approach for the issue
it was working around.
configs:
- config-6.12: unset new configs not needed for all cortexa7/a9/a53
- cortexa53/config-default: added new CONFIG_PCI_IMX6_HOST config for cortexA53 (IMX8M)

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
