Well, how U-Boot is stored on the SD-Card is a decision that you take
based on the balance safety against comfortably.
Both are ok on my side. If we put u-boot.img in raw SD at a fixed
address, it is very uncommon that a user destroy accessing it. On the
other side, putting it into a FAT partition makes easier to update for
everybody - just copying it into a disk.
The issue reported by Fabio is like a corrupted SD-Card - the SD-Card
does not contain the correct bootloader and it is ok if it does not boot
or hangs. Both ways have advantages and disadvantages.

Regards,
Stefano
