[PATCH v2 0/2] Add support for read retry

Posted by Cheng Ming Lin 1 week, 1 day ago

From: Cheng Ming Lin <chengminglin@mxic.com.tw>

When the host ECC fails to correct the data error of NAND device,
there's a special read for data recovery method which host executes
the Special Read for Data Recovery operation and may recover the
lost data by host ECC again.

For more detailed information, please refer to page 27 in the link below:
