Is it expected that you're not building any bootloader here?

Also, this needs a readme.txt to explain how to use this defconfig. If
you're putting off SD card, then please use genimage to generate a
complete SD card image. If you're booting out of NAND, please include
instructions on how to flash the resulting system.

But does it make sense to have a defconfig for a SOM ? A SOM as-is
generally can't be booted, it needs to be put on some base-board,
right ?

Best regards,

Thomas
