mtd: rawnand: rockchip: NFC driver for RK3308, RK2928 and others
This driver supports Rockchip NFC (NAND Flash Controller) found on RK3308, RK2928, RKPX30, RV1108 and other SOCs. The driver has been tested using 8-bit NAND interface on the ARM based RK3308 platform. Support Rockchip SoCs and NFC versions: - PX30 and RK3326(NFCv900). ECC: 16/40/60/70 bits/1KB. CLOCK: ahb and nfc. - RK3308 and RV1108(NFCv800). ECC: 16 bits/1KB. CLOCK: ahb and nfc. - RK3036 and RK3128(NFCv622). ECC: 16/24/40/60 bits/1KB. CLOCK: ahb and nfc. - RK3066, RK3188 and RK2928(NFCv600). ECC: 16/24/40/60 bits/1KB. CLOCK: ahb. Supported features: - Read full page data by DMA. - Support HW ECC(one step is 1KB). - Support 2 - 32K page size. - Support 8 CS(depend on SoCs) Limitations: - No support for the ecc step size is 512. - Untested on some SoCs. - No support for subpages. - No support for the builtin randomizer. - The original bad block mask is not supported. It is recommended to use the BBT(bad block table).
