The 64bit nature could complicate the compare code a little, and
we are limited to those 4KiB as you know. Mhm. It should be than
a comparission of a 64bit value instead of a 32bit one.
For us it is dangerous to exchange that code, since it is in NAND
block 0 and where an interrupted write process would kill our system.
It would be good to keep the old field for backward-compatibility
reasons, so that we do not have to update this piece of the boot-code.
