mtd: nand: raw: Drop SYS_NAND_SOFT_ECC from NAND_SANDBOX

2025-11-18T19:07:41Z

This option is only meaningful within the davinci nand driver, so drop the statement here (which had no effect). Signed-off-by: Tom Rini

mtd: spinand: add support for FudanMicro FM25S01A

2025-11-18T19:07:41Z

Add support for FudanMicro FM25S01A SPI NAND. This driver is ported from linux v6.18 and tested on a MT7981 board. Link: https://lore.kernel.org/linux-mtd/20250824170013.3328777-1-cnsztl@gmail.com/ Reviewed-by: Mikhail Kshevetskiy Signed-off-by: Tianling Shen

nand: raw: Kconfig: Correct some dependency issues

2025-11-18T19:06:17Z

The hidden symbol SPL_SYS_NAND_SELF_INIT was not being used correctly leading to Kconfig dependency issues seen with "make allyesconfig". As it's a select'd symbol we don't need to have a depends line on it, and then in turn we need to also update the logic on SYS_NAND_PAGE_SIZE and SYS_NAND_OOBSIZE. Signed-off-by: Tom Rini

mtd: spinor: winbond: Describe several chips

2025-11-18T19:05:59Z

All these chips are dual and quad capable. They are also DTR capable, but the core is not yet ready for that. Performances of all chips are comparable at 30MHz and are as follow: Eraseblock single read speed: 938kiB/s Eraseblock dual read speed: 1068kiB/s Eraseblock quad read speed: 3751kiB/s Signed-off-by: Miquel Raynal

mtd: nvmxip: Make use of LBAF for printing lbaint_t

2025-10-28T18:22:46Z

When printing the contents of an lbaint_t variable we need to use LBAF to print it in order to get the correct format type depending on 32 or 64bit-ness. Signed-off-by: Tom Rini

mtd: spi: sf_dataflash.c: Make use of 'z' for printing size_t

2025-10-28T18:21:31Z

When printing the contents of an size_t variable we need to use z prefix to the format character in order to get the correct format type depending on 32 or 64bit-ness. Signed-off-by: Tom Rini

mtd: Correct dependency on SYS_FLASH_CHECKSUM

2025-10-28T18:20:18Z

This feature requires that CFG_SYS_FLASH_BASE is defined and this in turn is only done in the case of FLASH_CFI_DRIVER && !CFI_FLASH or in other words, when DM_MTD is not enabled. Signed-off-by: Tom Rini

mtd: nand: Prevent dereference of NULL pointer

2025-10-28T18:11:09Z

In nand_wait_ready there is a loop that includes a NULL check for chip->dev_ready before it is dereferenced. Use a NULL check once the loop is exited as well to cover the case where it exits due to a timeout and it is therefore not known if chip->dev_ready is NULL or not. This issue found by Smatch.

Merge branch 'uboot-05102025' of https://source.denx.de/u-boot/custodians/u-boot-nand-flash

2025-10-10T14:24:45Z

This series adds significant and valuable work by Mikhail Kshevetskiy to align spi-mem with Linux 6.16. It also includes contributions to the mtd performance patches, a work started by Miquel Raynal and improved by Mikhail Kshevetskiy. Additionally, two patches tighten dependencies on the Atmel driver. The patches pass the pipeline CI: https://source.denx.de/u-boot/custodians/u-boot-nand-flash/-/pipelines/27873

nand: atmel: Rework ATMEL_EBI and DM_NAND_ATMEL interaction

2025-10-09T18:57:27Z

The way that the NAND driver under DM_NAND_ATMEL is probed is by the dummy memory driver controlled by ATMEL_EBI. Rather than require that for NAND to work both be enabled, make NAND select ATMEL_EBI and do not prompt for ATMEL_EBI as it only triggers the probe for NAND.
