I agreed with Paul and also Gianluca. I'm the u-boot maintainer for many Marvell Kirkwood SoC boards. All these boards are actively maintained and up to modern standard, i.e. can boot with file systems on SATA, USB, MMC... We can ignore what's currently in flash partitions and boot with kernels on disk rootfs.
What can I do to help in upgrading the update procedure to boot Debian 12 on Marvell Kirkwood SoCs? can somebody give me some pointer where to start looking for these scripts?
All the best,
Tony
