Booting from Nand is always a pain, not only on i.MX. SoC vendors are
always very creative when it comes to bad block handling and ECC layout.
Since it's the ROM code that reads the initial portion you are forced to
put on Nand whatever the ROM code wants to have, even if you want to use
a completely different ECC layout / Bad block table on your Nand.
