We thougt about that already, but nobody made an attempt to do so,
because we had no hardware supporting this.
I was thinking about a similar hook as it is used for command function
and dev_ready function. So the hardware ecc support would be located in
the corresponding hardware driver.
If you send me a diff against current CVS, we can find a clean way
together to incorporate it into nand.c
