Somehow I think handling the `.fcfield` is not needed when flashing with an offset, as long as `IMAGE_OFFSET > FCFIELD_END='0x410'`.

https://cache.freescale.com/files/microcontrollers/doc/app_note/AN4507.pdf

For me it seems like this `flash configuration field` is at a fixed address and not relative to the `jump address`. If we can confirm this, it makes things way easier.

And we could just say "We do not want to try flashing a binary if it does not start at 0 or is over `FCFIELD_END`". It somebody really want to handle it in the future, he can verify that the right bits are correct.

Even if the `.fcfield` is not required with an offset, we can still use the same linkerscript anyway, its just "wasting" 40bytes or something.
