U-boot comes with a default environment and scripts in that, we do not
modify that part (for the boards I know about).

It typically finds the efi boot loader and that loads NetBSD from the FFS

U-boot comes with its own DTB build in. The dtb files in the FAT partition
are passed to the NetBSD kernel (if one matching your board is found, otherwise
the u-boot build in one is used).
