No, as I wrote those systems have a board-specific bootloader on the board, not the OS media, that knows the correct dtb name for the board. There is no 'boot script on the SD card' needed for these kind of SoC.
My main point was that the fact that this works with some particular configuration which Fujitsu happens to use doesn't mean that it will work everywhere unless there is some sort of standardisation going on in this area, tailoring something to work with the Fujitsu setup is not all that useful.
Yes I agree. But no tailoring is being asked for,
it's an example of a setup where you can move one SD card around between different SoC systems using same kernel and multiple dtb.
I gave that example because you asked for use-cases where it was useful dumping all the DTBs on the card instead of the DTB matching the system it was installed on.
I did yes, sorry, got confused with other subthreads!
