MEMBERS
mode
ECC mode
steps
number of ECC steps per page
size
data bytes per ECC step
bytes
ECC bytes per step
total
total number of ECC bytes per page
strength
max number of correctible bits per ECC step
prepad
padding information for syndrome based ECC generators
postpad
padding information for syndrome based ECC generators
layout
ECC layout control struct pointer
priv
pointer to private ECC control data
hwctl
function to control hardware ECC generator. Must only be provided if an hardware ECC is available
calculate
function for ECC calculation or readback from ECC hardware

function to read a page according to the ECC generator requirements; returns maximum number of bitflips corrected in any single ECC
step, 0 if bitflips uncorrectable, -EIO hw error
read_subpage
function to read parts of the page covered by ECC; returns same as read_page
write_subpage
function to write parts of the page covered by ECC.
write_page
function to write a page according to the ECC generator requirements.

function to read chip OOB data without ECC
read_oob
function to read chip OOB data
write_oob
function to write chip OOB data
