commit e6031b11544b44966ba020c867fe438bccd3bdfa upstream.
The minimum size to fetch the data from device to QPIC buffer is 512-bytes. If size is less than 512-bytes the data will not be protected by ECC as per QPIC standard. So while reading onfi parameter page from NAND device set nandc->buf_count = 512.
