           It can be 2, 4, 8, 12 or 24.
        2. The PMECC sector size: CONFIG_PMECC_SECTOR_SIZE.
           It only can be 512 or 1024.
-       3. The PMECC index lookup table's offsets in ROM code: CONFIG_PMECC_INDEX_TABLE_OFFSET.
-          In the chip datasheet section "Boot Stragegies", you can find
-          two Galois Field Table in the ROM code. One table is for 512-bytes
-          sector. Another is for 1024-byte sector. Each Galois Field includes
-          two sub-table: indext table & alpha table.
-          In the beginning of each Galois Field Table is the index table,
-          Alpha table is in the following.
-          So the index table's offset is same as the Galois Field Table.
-
-          Please set CONFIG_PMECC_INDEX_TABLE_OFFSET correctly according the
-          Galois Field Table's offset base on the sector size you used.
