- 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.
