- num-cs: Number of chipselect lines to usw
- nand-on-flash-bbt: boolean to enable on flash bbt option if
not present false
- nand-ecc-strength: number of bits to correct per ECC step
- nand-ecc-step-size: number of data bytes covered by a single ECC step
The following ECC strength and step size are currently supported:
- nand-ecc-strength = <1>, nand-ecc-step-size = <512>
- nand-ecc-strength = <4>, nand-ecc-step-size = <512>
- nand-ecc-strength = <8>, nand-ecc-step-size = <512>
