Hello, I've got multiple ARM boards with similar but not quite the same configurations. For example different IO configurations for peripheral reset lines of hardware used in the u-boot phase.
Currently I have multiple u-Boot configurations using multiple .dts files creating multiple u-boot.img and MLO files which are stored on the devices emmc (one set on every device). The u-boot than loads the linux kernel and the device specific linux dtb from a FAT partition on the device and boots (The linux partition has one kernel and multiple .dtb, so it supports all devices). The differences between the boards are GPIO related, but also power configuration & regulator settings. I would prefer to have a single u-boot.img and MLO file set to load onto all my devices. When I search the docs for this issue, I find many hints pointing me to u-boot FIT images, but from my point of view FIT issues multiple LINUX kernel and dt-blobs, not dt-blobs and configuration on the u-boot level. What would be the cleanest solution to load one uboot image, which has different behavior depending on the device it boots from?
