-Subject: [PATCH 10/15] mtd: nand: fix ecc parameters for mt7622
-
-According to the datasheet, mt7622 only has 5 ECC capabilities instead
-of 7, and the decoding error register is arranged  as follows:
-+------+---------+---------+---------+---------+
-| Bits |  19:15  |  14:10  |   9:5   |   4:0   |
-+------+---------+---------+---------+---------+
-| Name | ERRNUM3 | ERRNUM2 | ERRNUM1 | ERRNUM0 |
-+------+---------+---------+---------+---------+
-This means err_mask should be 0x1f instead of 0x3f and the number of
-bits shifted in mtk_ecc_get_stats should be 5 instead of 8.
-
-This commit introduces err_shift for the difference in this register
-and fix other existing parameters.
-
-Public MT7622 reference manual can be found on [0] and the info this
-commit is based on is from page 656 and page 660.
