We used to write the second firmware right after the first
firmware. However, splitting the available space into two
equal regions has advantages: When we update barebox the next
time the generated FCB/DBBT blocks will be the same as with the
last update, so in case of power failure it is more likely that
we have valid data in one of the FCB/DBBT areas.

Now that we use a partition for the bootloader instead of
the whole NAND device we can erase it completely instead of
hardcoded 2MB.

We used to put the FCB in the first two NAND blocks and the DBBT
in the third and fourth block. It's much more space efficient to
put the FCB and DBBT together into the same eraseblock in different
pages. This way we can store four FCBs and four DBBTs instead of
two only.

The code can be used with slight modifications on i.MX28 aswell.
Add a i.MX28 registration function and move the differences to
function callbacks.

We used to use nand0 device for storing barebox and made the assumption
that there is enough space at the beginning of the first device. Instead,
use the barebox partition directly. This requires that the partition
where barebox should be stored is named 'barebox', that is the case for
all boards currently.

We should print the block number before increasing it, not afterwards.

The code can be used on i.MX28 aswell, so move it to a common place.
