mtd: nand: mxic-ecc: Add Macronix external ECC engine support

2022-02-09T08:49:25Z

Some SPI-NAND chips do not support on-die ECC. For these chips, correction must apply on the SPI controller end. In order to avoid doing all the calculations by software, Macronix provides a specific engine that can offload the intensive work. Add Macronix ECC engine support, this engine can work in conjunction with a SPI controller and a raw NAND controller, it can be pipelined or external and supports linear and syndrome layouts. Right now the simplest configuration is supported: SPI controller external and linear ECC engine.

mtd: nand: ecc-hamming: Move Hamming code to the generic NAND layer

2020-12-10T21:37:29Z

Hamming ECC code might be later re-used by the SPI NAND layer. Signed-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20200929230124.31491-12-miquel.raynal@bootlin.com

mtd: nand: ecc-bch: Move BCH code to the generic NAND layer

BCH ECC code might be later re-used by the SPI NAND layer. Signed-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20200929230124.31491-3-miquel.raynal@bootlin.com

mtd: nand: Introduce the ECC engine framework

2020-09-02T07:28:15Z

Create a generic ECC engine framework. This is a base to instantiate ECC engine objects. If we really want to be generic, bindings must evolve, so here is the new logic. The following three properties are mutually exclusive: - The nand-no-ecc-engine boolean property is set and there is no ECC engine to retrieve. - The nand-use-soft-ecc-engine boolean property is set and the core will force using the use of software correction. - There is a nand-ecc-engine property pointing at a node which will act as ECC engine. It the later case, the property may reference: - The NAND chip node itself (for the on-die ECC case). - The parent node if the NAND controller embeds an ECC engine. - Any other node being an external ECC controller as well.

mtd: nand: Add core infrastructure to support SPI NANDs

2018-07-18T07:24:10Z

Add a SPI NAND framework based on the generic NAND framework and the spi-mem infrastructure. In its current state, this framework supports the following features: - single/dual/quad IO modes - on-die ECC Signed-off-by: Peter Pan Signed-off-by: Boris Brezillon Signed-off-by: Miquel Raynal

mtd: Move onenand code base to drivers/mtd/nand/onenand

2018-03-15T14:40:37Z

Move onenand code base to the drivers/mtd/nand directory in the hope that someday someone will patch it to use the generic NAND helpers. If it never happens, at least we'll have all NAND related support in a single directory and not spread over the drivers/mtd/ directory. Signed-off-by: Boris Brezillon

mtd: nand: Add core infrastructure to deal with NAND devices

2018-02-16T09:10:53Z

Add an intermediate layer to abstract NAND device interface so that some logic can be shared between SPI NANDs, parallel/raw NANDs, OneNANDs, ... Signed-off-by: Boris Brezillon

mtd: nand: move raw NAND related code to the raw/ subdir

2018-02-16T09:09:34Z

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

mtd: nand: Get rid of comments giving the file path inside the file itself

2018-02-16T09:08:27Z

Some files add a comment giving the path of the file inside the Linux tree, which is pretty useless since the reader had to find the file to open it. Getting rid of these comments will also allow us to easily move these files around when needed. Signed-off-by: Boris Brezillon
