* mtd: nand: move raw NAND related code to the raw/ subdirBoris Brezillon2018-02-161-416/+0
| | | | | | | | As part of the process of sharing more code between different NAND based devices, we need to move all raw NAND related code to the raw/ subdirectory. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>
* mtd: nand: Rename nand.h into rawnand.hBoris Brezillon2017-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | We are planning to share more code between different NAND based devices (SPI NAND, OneNAND and raw NANDs), but before doing that we need to move the existing include/linux/mtd/nand.h file into include/linux/mtd/rawnand.h so we can later create a nand.h header containing all common structure and function prototypes.

* mtd: nand: jz4780: Use mtd_set_ooblayout() to set the ooblayoutBoris Brezillon2017-05-151-1/+1
| | | | | | | | | The mtd_set_ooblayout() accesor has been added to hide internals of mtd_info and ease future refactoring. Call mtd_set_ooblayout() instead of directly accessing mtd->ooblayout.

* mtd: mtd: drop NAND_ECC_SOFT_BCH enum valueRafał Miłecki2016-05-051-1/+0
| | | | | | | | | This value should not be part of nand_ecc_modes_t as it specifies algorithm not a mode. We successfully managed to introduce new "algo" field which is respected now. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
* mtd: nand: jz4780: switch to mtd_ooblayout_opsBoris Brezillon2016-05-051-14/+5
| | | | | | | | Implementing the mtd_ooblayout_ops interface is the new way of exposing ECC/OOB layout to MTD users. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Tested-by: Harvey Hunt <harvey.hunt@imgtec.com>
* mtd: nand: remove unneeded of_mtd.h inclusionsBoris Brezillon2016-04-191-1/+0
| | | | | | | | Some drivers are including linux/of_mtd.h even if they don't use any of the of_get_nand_xxx() helpers. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Acked-by: Harvey Hunt <harvey.hunt@imgtec.com>
* mtd: jz4780_nand: replace if/else blocks with switch/caseBrian Norris2016-01-081-15/+19
| | | | | | | | | | | | | | | | | Using switch/case helps make this logic more clear and more robust. With this structure: * it's clear that this driver only support ECC_{HW,SOFT,SOFT_BCH}; and * we can sanely handle new ECC unsupported modes (right now, this code makes incorrect assumptions about the possible values in the nand_ecc_modes_t enum; e.g., what happens with NAND_ECC_HW_OOB_FIRST?)

* mtd: jz4780_nand: remove useless mtd->priv = chip assignmentBrian Norris2016-01-071-1/+0
| | | | | | | | | | | As of commit 2d3b77bac34b ("mtd: nand: update mtd_to_nand()"), this assignment isn't necessary, since struct mtd_info is embedded in struct nand_chip.

* mtd: nand: jz4780: driver for NAND devices on JZ4780 SoCsAlex Smith2016-01-071-0/+425
Add a driver for NAND devices connected to the NEMC on JZ4780 SoCs, as well as the hardware BCH controller. DMA is not currently implemented. While older 47xx SoCs also have a BCH controller, they are incompatible with the one in the 4780 due to differing register/bit positions, which would make implementing a common driver for them quite messy.
