@ -47,6 +47,11 @@ Optional properties:
partitions written from Linux with this feature
turned on may not be accessible by the BootROM
code.
- nand-ecc-strength: integer representing the number of bits to correct
per ECC step. Needs to be a multiple of 2.
- nand-ecc-step-size: integer representing the number of data bytes
that are covered by a single ECC step. The driver
supports 512 and 1024.
The device tree may optionally contain sub-nodes describing partitions of the
address space. See partition.txt for more detail.
