2022-03-07mtd: rawnand: omap2: Actually prevent invalid configuration and build errorRoger Quadros1-2/+1
The root of the problem is that we are selecting symbols that have dependencies. This can cause random configurations that can fail. The cleanest solution is to avoid using select. This driver uses interfaces from the OMAP_GPMC driver so we have to depend on it instead.

2022-01-23mtd: rawnand: brcmnand: Add BCMA shimFlorian Fainelli1-0/+13
Add a BCMA shim to allow us to register the brcmnand driver using the BCMA bus which provides indirect memory mapped access to SoC registers. There are a number of registers that need to be byte swapped because they are natively big endian, coming directly from the NAND chip, and there is no bus interface unlike the iProc or STB platforms that performs the byte swapping for us.

The Ericsson U300 platform was one of two ARM929 based SoC platforms for mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP into ST-Ericsson, the other one being the ST Nomadik. The platform was not widely adopted in Linux based systems and was replaced with the far superior ST-Ericsson U8500 in 2011, but Linus Walleij kept maintaining the code for the whole time. Linus continues to use the Nomadik machine, but decided to drop u300 from the kernel as part of this year's spring cleaning. Thanks for having maintained it all these years.

Add support for the hardware ECC BCH engine. Please mind that this engine has an important limitation: BCH implementation does not inform the user when an uncorrectable ECC error occurs. To workaround this, we avoid using the hardware engine in the read path and do the computation with the software BCH implementation, which is faster than mixing hardware (for correction) and software (for verification).

The driver adds the support for the STMicroelectronics FMC2 NAND Controller found on STM32MP SOCs. This patch is based on FMC2 command sequencer. The purpose of the command sequencer is to facilitate the programming and the reading of NAND flash pages with the ECC and to free the CPU of sequencing tasks. It requires one DMA channel for write and two DMA channels for read operations. Only NAND_ECC_HW mode is actually supported. The driver supports a maximum 8k page size. The following ECC strength and step size are currently supported: - nand-ecc-strength = <8>, nand-ecc-step-size = <512> (BCH8) - nand-ecc-strength = <4>, nand-ecc-step-size = <512> (BCH4) - nand-ecc-strength = <1>, nand-ecc-step-size = <512> (Extended ECC based on Hamming) This patch has been tested on Micron MT29F8G08ABACAH4 and MT29F8G16ABACAH4 Signed-off-by: Christophe Kerello <christophe.kerello@st.com> Reviewed-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

2018-10-03mtd: rawnand: Remove docg4Boris Brezillon1-20/+0
The diskonchip G4 driver does not fit very well in the raw/parallel NAND framework simply because such chips have an internal controller translating DoC-specific commands into NAND ones. Keeping such a driver in the raw NAND framework is a real burden for NAND maintainers. Not to mention that some parts of this driver are a bit worrisome: - writes are done by subpages, even though we're interfacing with an MLC chip which are known to not support subpage writes very well (it might be that the FTL handles the complexity for us though) - some part of the code are simply ignoring return codes of function that can fail in a few occasions - there's a hack to support OOB writes when no data is provided. This operation is not supported by the chip and should have been rejected, and nandwrite and other userspace tools should have been patched to deal with such devices - the driver is apparently broken when ignore_badblocks module param is not set to 1 and nobody noticed that (don't know since when this is the case, but it's not a recent change) http://lists.infradead.org/pipermail/linux-mtd/2018-July/082472.html Add to that the fact that we already have a docg3 driver in drivers/mtd/devices/docg3.c and, looking at the code (and regs), it seems docg3 and docg4 have a lot in common (even the author of this driver seemed to have realized that interfacing with the raw NAND framework might have been a bad idea http://lists.infradead.org/pipermail/linux-mtd/2012-January/039517.html). For all these reasons, I'm proposing to remove this driver. If anyone ever wants to add support for this chip back, I'd suggest extending the docg3 driver instead of adding a completely new driver.
