2019-02-05mtd: rawnand: stm32_fmc2: add STM32 FMC2 NAND flash controller driverChristophe Kerello1-0/+1
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 <[email protected]> Reviewed-by: Boris Brezillon <[email protected]> Signed-off-by: Miquel Raynal <[email protected]>

2018-10-03mtd: rawnand: Remove docg4Boris Brezillon1-1/+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.
