SPI NOR core changes: - Add Pratyush as SPI NOR co-maintainer. - Flash parameters initialization was done in a spaghetti way. Clean flash parameters initialization. - Rework the flash_info flags and clarify where one should be used. - Initialize all flash parameters based on JESD216 SFDP where possible. Flash parameters and settings that are SFDP discoverable should not be duplicated via flash_info flags at flash declaration. - Remove debugfs entries that duplicate sysfs entries. SPI NOR manufacturer drivers changes: - Use late_init() hook in various drivers to make it clear that those flash parameters are either not declared in the JESD216 SFDP standard, or the SFDP tables which define those flash parameters are not defined by the flash. - Fix mtd size for s3an flashes. - Write 2 bytes when disabling Octal DTR mode: 1 byte long transactions are not allowed in 8D-8D-8D mode.

mtd: Introduce an expert mode for forensics and debugging purposes

2021-12-09T16:51:59Z

When developping NAND controller drivers or when debugging filesystem corruptions, it is quite common to need hacking locally into the MTD/NAND core in order to get access to the content of the bad blocks. Instead of having multiple implementations out there let's provide a simple yet effective specific MTD-wide debugfs entry to fully disable these checks on purpose. A warning is added to inform the user when this mode gets enabled. Signed-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20211118114659.1282855-1-miquel.raynal@bootlin.com

mtd: rawnand: Export nand_read_page_hwecc_oob_first()

Move the function nand_read_page_hwecc_oob_first() (previously nand_davinci_read_page_hwecc_oob_first()) to nand_base.c, and export it as a GPL symbol, so that it can be used by more modules.

mtd: spi-nor: Get rid of nor->page_size

2021-11-17T12:41:26Z

nor->page_size duplicated what nor->params->page_size indicates for no good reason. page_size is a flash parameter of fixed value and it is better suited to be found in nor->params->page_size.

mtd: Remove obsolete macros only used by the old nand_ecclayout struct

2021-09-14T17:34:28Z

All uses of MTD_MAX_{OOBFREE,ECCPOS}_ENTRIES_LARGE have been removed as commit ef5eeea6e911 ("mtd: nand: brcm: switch to mtd_ooblayout_ops") and commit aab616e31d1c ("mtd: kill the nand_ecclayout struct") replaced struct nand_ecclayout by the new mtd_ooblayout_ops interface. Remove these two macros therefore. Reported-by: Yi Yang Signed-off-by: GONG, Ruiqi Signed-off-by: Miquel Raynal Link: https://lore.kernel.org/linux-mtd/20210830083356.31702-1-gongruiqi1@huawei.com
