flash based BBT for identifying bad blocks.
The dt property fsl,use-minimum-ecc requires a NAND chip to provide a ECC strength/step size, otherwise the driver fails to probe. This is by design to avoid that the driver uses a fallback and later changes ECC parameters due to additionion of a NAND chip driver. Document the current behavior.
