Kubernetes image for Mono Gateway Development Kit

https://docs.mono.si/gateway-development-kit/getting-started

The device's dts files are located at here

https://github.com/we-are-mono/OpenWRT-ASK/tree/mono-25.12.0-rc3/target/linux/layerscape/files/arch/arm64/boot/dts/freescale

We need both mono-gateway-dk-sdk.dts and mono-gateway-dk.dts since the sdk one includes the non-sdk one.
The actual dts being used is the mono-gateway-dk-sdk.dts

Build

To avoid frequent downloading on rebuild. Find and download the latest kernel and busybox. Put them into dev/nxplinux.tar.gz and dev/busybox.tar.gz respectively.

make itb # for out/board.itb
make release # WORK IN PROGRESS

Architecture

A/B deployment
Read-only OS

Upgrade process

Rough idea

./configure
# - join cluster config

make release


# Copy the new image to the upgrade-scheduler
kubectl cp -n kube-system upgrade-scheduler:/tmp/upgrade.img

# Upgrade scheduler reads the file that issue a self-reboot
reboot

# uboot to boot into partition B

PENDING

tftp (network is required)

setenv ipaddr 10.0.0.153
setenv serverip 10.0.0.129
tftp 0x80000000 board.itb

USB
