mtd: nand: Add a helper to retrieve the number of pages per target

2019-04-08T08:21:09+00:00

Will be used by the raw NAND framework. Signed-off-by: Boris Brezillon Signed-off-by: Miquel Raynal Reviewed-by: Frieder Schrempf

mtd: nand: Add a helper returning the number of eraseblocks per target

2019-04-08T08:21:09+00:00

Some drivers in the raw NAND framework seems to need this helper, so let's just add it instead of open-coding the logic. Signed-off-by: Boris Brezillon Signed-off-by: Miquel Raynal Reviewed-by: Frieder Schrempf

mtd: nand: Add max_bad_eraseblocks_per_lun info to memorg

2019-04-08T08:21:08+00:00

NAND datasheets usually give the maximum number of bad blocks per LUN and this number can be used to help upper layers decide how much blocks they should reserve for bad block handling. Add a max_bad_eraseblocks_per_lun to the nand_memory_organization struct and update the NAND_MEMORG() macro (and its users) accordingly. We also provide a default mtd->_max_bad_blocks() implementation. Signed-off-by: Boris Brezillon Signed-off-by: Miquel Raynal Reviewed-by: Frieder Schrempf

mtd: nand: Fix nanddev_pos_next_page() kernel-doc header

2018-11-06T16:40:31+00:00

Function name is wrong in the kernel-doc header. Fixes: 9c3736a3de21 ("mtd: nand: Add core infrastructure to deal with NAND devices") Signed-off-by: Boris Brezillon Reviewed-by: Miquel Raynal

mtd: nand: Fix nanddev_neraseblocks()

2018-11-05T08:23:47+00:00

nanddev_neraseblocks() currently returns the number pages per LUN instead of the total number of eraseblocks. Fixes: 9c3736a3de21 ("mtd: nand: Add core infrastructure to deal with NAND devices") Cc: Signed-off-by: Boris Brezillon Reviewed-by: Miquel Raynal

mtd: nand: Pass mode information to nand_page_io_req

2018-06-01T12:53:50+00:00

The NAND sub-layers are likely to need the MTD_OPS_XXX mode information in order to decide if they should enable/disable ECC or how they should place the OOB bytes in the provided OOB buffer. Add a field to nand_page_io_req to pass this information. Signed-off-by: Boris Brezillon Reviewed-by: Miquel Raynal Tested-by: Frieder Schrempf Reviewed-by: Frieder Schrempf

mtd: nand: Rename nand.h into rawnand.h

2017-08-13T08:11:49+00:00

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.

Pull MTD updates from Brian Norris: "General updates: - Cleanups and additional flash support for "dataflash" driver - new driver for mchp23k256 SPI SRAM device - improve handling of MTDs without eraseblocks (i.e., MTD_NO_ERASE) - refactor and improve "sub-partition" handling with TRX partition parser; partitions can now be created as sub-partitions of another partition SPINOR updates, from Cyrille Pitchen and Marek Vasut: - introduce support to the SPI 1-2-2 and 1-4-4 protocols. - introduce support to the Double Data Rate (DDR) mode. - introduce support to the Octo SPI protocols. - add support to new memory parts for Spansion, Macronix and Winbond. - add fixes for the Aspeed, STM32 and Cadence QSPI controler drivers. - clean up the st_spi_fsm driver. NAND updates, from Boris Brezillon: - addition of on-die ECC support to Micron driver - addition of helpers to help drivers choose most appropriate ECC settings - deletion of dead-code (cached programming and ->errstat() hook) - make sure drivers that do not support the SET/GET FEATURES command return ENOTSUPP use a dummy ->set/get_features implementation returning -ENOTSUPP (required for Micron on-die ECC) - change the semantic of ecc->write_page() for drivers setting the NAND_ECC_CUSTOM_PAGE_ACCESS flag - support exiting 'GET STATUS' command in default ->cmdfunc() implementations - change the prototype of ->setup_data_interface() A bunch of driver related changes: - various cleanup, fixes and improvements of the MTK driver - OMAP DT bindings fixes - support for ->setup_data_interface() in the fsmc driver - support for imx7 in the gpmi driver - finalization of the denali driver rework (thanks to Masahiro for the work he's done on this driver) - fix "bitflips in erased pages" handling in the ifc driver - addition of PM ops and dynamic timing configuration to the atmel driver" * tag 'for-linus-20170713' of git://git.infradead.org/linux-mtd: (118 commits) Documentation: ABI: mtd: describe "offset" more precisely mtd: Fix check in mtd_unpoint() mtd: nand: mtk: release lock on error path mtd: st_spi_fsm: remove SPINOR_OP_RDSR2 and use SPINOR_OP_RDCR instead mtd: spi-nor: cqspi: remove duplicate const mtd: spi-nor: Add support for Spansion S25FL064L mtd: spi-nor: Add support for mx66u51235f mtd: nand: mtk: add ->setup_data_interface() hook mtd: nand: mtk: remove unneeded mtk_ecc_hw_init from mtk_ecc_resume mtd: nand: mtk: remove unneeded mtk_nfc_hw_init from mtk_nfc_resume mtd: nand: mtk: disable ecc irq when writing page with hwecc mtd: nand: mtk: fix incorrect register setting order about ecc irq mtd: partitions: fixup some allocate_partition() whitespace mtd: parsers: trx: fix pr_err format for printing offset MAINTAINERS: Update SPI NOR subsystem git repositories mtd: extract TRX parser out of bcm47xxpart into a separated module mtd: partitions: add support for partition parsers mtd: partitions: add support for subpartitions mtd: partitions: rename "master" to the "parent" where appropriate mtd: partitions: remove sysfs files when deleting all master's partitions ...
