As XEA board uses imx287, which has some constrains on SPL (u-boot.sb) size - it must be less than ~55 KiB, multiple boards versions are included in u-boot proper's FIT image.
The decision of using proper configuration is based on information passed from SPL (u-boot.sb) in OCRAM dedicated location (0xE000 - 2).
This board also uses falcon boot for production setup, so the proper dtb is flashed during production (also based on GPIO values describing HW ID).
