Why change the ECC layout?
Be very careful when you change ECC layouts. This can break production
For example if people are running something earlier and then want to deliver a
new kernel with 2.6.37 then their existing NAND file systems will no longer
Changes to ECC should only be done for very good reasons and should be
controlled with a Kconfig with the default being the existing ECC layout.
