- Subject: [PATCH 1/2] mtd: rawnand: add driver support for MT7621 nand
- flash controller
- This patch adds NAND flash controller driver for MediaTek MT7621 SoC.
- The NAND flash controller is similar with controllers described in
- mtk_nand.c, except that the controller from MT7621 doesn't support DMA
- transmission, and some registers' offset and fields are different.
