[PATCH v1 0/2] arm64: dts: imx8mp: add support for the ABB SoM and carrier

From: Heiko Schocher
Date: Mon Oct 28 2024 - 04:24:12 EST


The board uses a ABB specific SoM from ADLink, based on NXP
i.MX8MP SoC. The SoM is used on 3 different carrier boards,
with small differences, which are all catched up in
devicetree overlays. The kernel image, the basic dtb
and all dtbos are collected in a fitimage. As bootloader
is used U-Boot which detects in his SPL stage the carrier
board by probing some i2c devices. When the correct
carrier is probed, the SPL applies all needed dtbos to
the dtb with which U-Boot gets loaded. Same principle
later before linux image boot, U-Boot applies the dtbos
needed for the carrier board before booting Linux.

So intentionally, there are no full dtb images for all
carrier combinations, only dtbos which applied as needed
on boottime.

Patches to U-Boot mailinglist not posted yet, as U-Boot
uses the same dtb as linux, so hope to get the linux
files first in, and use them when posting U-Boot board
support.

series is based on:
819837584309 - (tag: v6.12-rc5, origin/master, origin/HEAD) Linux 6.12-rc5
