This can be disabled by parameter in the FCB (at least according to
the i.MX6 reference Manual):
from imx28's reference manual, there is not such bit in the FCB to
disable the
swapping. But you are disabling the swapping in the imx28's DTS file,
isn't it?
I think it is dangerous.
|DISBBM 172 4 If 0 ROM will swap BadBlockMarkerByte with
| metadata[0] after reading a page using BCH40.
| If the value set is 1 then ROM will not do

I will consult with our ROM colleague about this DISBBM bit.
I am not sure if the ROM still do the swapping for the uboot when we set
DISBBM bit.
thanks
