|  | - nand-ecc-mode : String, operation mode of the NAND ecc mode. | 
|  | Supported values are: "none", "soft", "hw", "hw_syndrome", "hw_oob_first", | 
|  | "soft_bch". | 
|  | - nand-bus-width : 8 or 16 bus width if not present 8 | 
|  | - nand-on-flash-bbt: boolean to enable on flash bbt option if not present false | 
|  |  | 
|  | - nand-ecc-strength: integer representing the number of bits to correct | 
|  | per ECC step. | 
|  |  | 
|  | - nand-ecc-step-size: integer representing the number of data bytes | 
|  | that are covered by a single ECC step. | 
|  |  | 
|  | The ECC strength and ECC step size properties define the correction capability | 
|  | of a controller. Together, they say a controller can correct "{strength} bit | 
|  | errors per {size} bytes". | 
|  |  | 
|  | The interpretation of these parameters is implementation-defined, so not all | 
|  | implementations must support all possible combinations. However, implementations | 
|  | are encouraged to further specify the value(s) they support. |
