Yes, some boards/bootloader configuration have the limitation that the
first partition must be a FAT partition. In this case, it definitely
makes sense to have two partitions, since a Linux root filesystem can
hardly be stored in a FAT filesystem.

Well, in the situation of this board, where the bootloader is stored
raw and is capable of reading an ext2 filesystem, yes I believe a
single partition makes more sense.

You can ask Buildroot to install the uImage and DTB to /boot in the
root filesystem. However, for the extlinux.config file, you'll have to
add a post-build script to do this.

Best regards,

Thomas
