be1d1a76 - mtd: spi-nor: Remove support for Xilinx S3AN flashes

Fri, 19 Apr 2024 14:12:44 +0000

mtd: spi-nor: Remove support for Xilinx S3AN flashesThese flashes are kind of an oddball for the very old Xilinx Spartan 3FPGAs to store their bitstream. More importantly, they reuse the AtmelJEDEC manufacturer ID and in fact the at45db081d already blocks the useof the 3S700AN flash chip. It's time to sunset support for theseflashes.Signed-off-by: Michael Walle Acked-by: Tudor Ambarus Reviewed-by: Pratyush Yadav Cc: Ricardo Ribalda Acked-by: Ricardo Ribalda Signed-off-by: Pratyush Yadav Link: https://lore.kernel.org/r/20240419141249.609534-2-mwalle@kernel.org List of files: /linux-6.15/drivers/mtd/spi-nor/Makefile

mtd: spi-nor: remove Fujitsu MB85RS1MT supportThis part is not a flash but an EEPROM like FRAM. It is even has a DTbinding for the (correct) driver (at25), seeDocumentation/devicetree/bindings/eeprom/at25.yaml. Just remove it.Signed-off-by: Michael Walle Link: https://lore.kernel.org/r/20230807-mtd-flash-info-db-rework-v3-2-e60548861b10@kernel.orgSigned-off-by: Tudor Ambarus List of files: /linux-6.15/drivers/mtd/spi-nor/Makefile

0257be79 - mtd: spi-nor: expose internal parameters via debugfs

Fri, 29 Apr 2022 10:20:18 +0000

mtd: spi-nor: expose internal parameters via debugfsThere is no way to gather all information to verify support for a newflash chip. Also if you want to convert an existing flash chip to thenew SFDP parsing, there is not enough information to determine if theflash will work like before. To ease this development, expose internalparameters via the debugfs.Signed-off-by: Michael Walle Signed-off-by: Pratyush Yadav Reviewed-by: Pratyush Yadav Link: https://lore.kernel.org/r/20220429102018.2361038-2-michael@walle.cc List of files: /linux-6.15/drivers/mtd/spi-nor/Makefile

mtd: spi-nor: add initial sysfs supportAdd support to show the manufacturer, the partname and JEDEC identifieras well as to dump the SFDP table.

069089ac - mtd: spi-nor: add OTP support

Sun, 21 Mar 2021 23:51:38 +0000

mtd: spi-nor: add OTP supportSPI flashes sometimes have a special OTP area, which can (and is) used tostore immutable properties like board serial number or vendor assignednetwork hardware addresses.The MTD subsystem already supports accessing such areas and some (nonSPI NOR) flashes already implement support for it. It differentiatesbetween user and factory areas. User areas can be written by the user andfactory ones are pre-programmed and locked down by the vendor, usuallycontaining an "electrical serial number". This patch will only add supportfor the user areas.Lay the foundation and implement the MTD callbacks for the SPI NOR and addnecessary parameters to the flash_info structure. If a flash supports OTPit can be added by the convenience macro OTP_INFO(). Sometimes there areindividual regions, which might have individual offsets. Therefore, it ispossible to specify the starting address of the first regions as well asthe distance between two regions (e.g. Winbond devices uses this method).Additionally, the regions might be locked down. Once locked, no furtherwrite access is possible.For SPI NOR flashes the OTP area is accessed like the normal memory, e.g.by offset addressing; except that you either have to use special read/writecommands (Winbond) or you have to enter (and exit) a specific OTP mode(Macronix, Micron).Thus we introduce four operations to which the MTD callbacks will bemapped: .read(), .write(), .lock() and .is_locked(). The read and the writeops will be given an address offset to operate on while the locking ops useregions because locking always affects a whole region. It is up to theflash driver to implement these ops.Signed-off-by: Michael Walle [ta: use div64_u64(), IS_ALIGNED, params->otp.org. unsigned int region,drop comment, add rlen local variable in spi_nor_mtd_otp_lock()]Signed-off-by: Tudor Ambarus Link: https://lore.kernel.org/r/20210321235140.8308-2-michael@walle.cc List of files: /linux-6.15/drivers/mtd/spi-nor/Makefile
