* ramips: correct page read return value of the mt7621 nand driverShiji Yang2023-05-22
| | | | | | | | | | | | | read_page() need to return maximum number of bitflips instead of the accumulated number. Change takes from upstream mt7621 u-boot [1]. * @read_page: function to read a page according to the ECC generator * requirements; returns maximum number of bitflips * corrected in any single ECC step, -EIO hw error [1] https://lore.kernel.org/all/cover.1653015383.git.weijie.gao@mediatek.com/ Signed-off-by: Shiji Yang <yangshiji66@qq.com>

* ramips: move mt7621_nand driver to filesStijn Tintel2022-03-25
The patch was rejected by upstream. The mtk_nand driver should be modified to support the mt7621 flash controller instead. As there is no newer version to backport, or no upstream version to fix bugs, let's move the driver to the files dir under the ramips target. This makes it easier to make changes to the driver while waiting for mt7621 support to land in mtk_nand. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
