ELM module can be used for error correction of BCH 4 & 8 bit. Also
support read & write page in one shot by adding custom read_page &
write_page methods. This helps in optimizing code.
New structure member "is_elm_used" is added to know the status of
whether the ELM module is used for error correc
11 matches
