2024-10-31mtd: spi-nor: Rename SPI_ADVANCE to SPI_STACKED_PARALLELMarek Vasut
The SPI_ADVANCE description does not explain what the switch does. It does not have anything to do with any advanced functionality, it only gates off support for stacked and parallel SPI NORs. Rename the Kconfig symbol, update description, and move it right next to Xilinx hardware as it seems to be specific to this hardware. Make sure the symbol is also protected by if DM_SPI in Kconfig.

2024-10-15mtd: spi-nor: Allow flashes to specify MTD writesizeTakahiro Kuwano
Some flashes like the Infineon SEMPER NOR flash family use ECC. Under this ECC scheme, multi-pass writes to an ECC block is not allowed. In other words, once data is programmed to an ECC block, it can't be programmed again without erasing it first. Upper layers like file systems need to be given this information so they do not cause error conditions on the flash by attempting multi-pass programming. This can be done by setting 'writesize' in 'struct mtd_info'. Set the default to 1 but allow flashes to modify it in fixup hooks. If more flashes show up with this constraint in the future it might be worth it to add it to 'struct flash_info', but for now increasing its size is not worth it. This patch replicates the following upstream linux commit: afd473e85827 ("mtd: spi-nor: core: Allow flashes to specify MTD writesize") Acked-by: Tudor Ambarus <[email protected]> Signed-off-by: Takahiro Kuwano <[email protected]>
2024-10-10mtd: spi-nor: Clear Winbond SR3 WPS bit on bootMarek Vasut
Some Winbond SPI NORs have special SR3 register which is used among other things to control whether non-standard "Individual Block/Sector Write Protection" (WPS bit) locking scheme is activated. This non-standard locking scheme is not supported by either U-Boot or Linux SPI NOR stack so make sure it is disabled, otherwise the SPI NOR may appear locked for no obvious reason. This SR3 WPS appears e.g. on W25Q16FW which has the same ID as W25Q16DW, but the W25Q16DW does not implement the SR3 WPS bit. Signed-off-by: Marek Vasut <[email protected]>
2024-10-09mtd: spi-nor: Add parallel and stacked memories supportVenkatesh Yadav Abbarapu
In parallel mode, the current implementation assumes that a maximum of two flashes are connected. The QSPI controller splits the data evenly between both the flashes so, both the flashes that are connected in parallel mode should be identical. During each operation SPI-NOR sets 0th bit for CS0 & 1st bit for CS1 in nor->flags. In stacked mode the current implementation assumes that a maximum of two flashes are connected and both the flashes are of same make but can differ in sizes. So, except the sizes all other flash parameters of both the flashes are identical Spi-nor will pass on the appropriate flash select flag to low level driver, and it will select pass all the data to that particular flash. Write operation in parallel mode are performed in page size * 2 chunks as each write operation results in writing both the flashes. For doubling the address space each operation is performed at addr/2 flash offset, where addr is the address specified by the user. Similarly for read and erase operations it will read from both flashes, so size and offset are divided by 2 and send to flash. Adding the config option SPI_ADVANCE for non SPL code.

2024-01-29mtd: spi-nor-core: Rework spi_nor_cypress_octal_dtr_enable()Takahiro Kuwano
Enabling Octal DTR mode in multi-die package parts requires reister setup for each die. That can be done by simple for-loop. write_enable() takes effect to all die at once so we can call it before the loop. Besides we can replace spi_mem_exec_op() calls with spansion_read/write_any_reg(). And finally, we must mask CFR2V[7:4] when changing dummy cycles, as CFR2V[7] indicates current addressing mode and that should be 1 (4-byte address mode) for multi-die package parts.

To quote the author: This series tests raw nand flash in sandbox and fixes various bugs discovered in the process.

Future work could test the rest of the nand API as well as the MTD API. Bloat (for v1) at [1] (for boards with SPL_NAND_SUPPORT enabled). Almost everything grows by a few bytes due to nand_page_size.

2023-10-13mtd/spinand: rework detect procedure for different READ_ID operationMikhail Kshevetskiy
Currently there are 3 different variants of read_id implementation: 1. opcode only. Found in GD5FxGQ4xF. 2. opcode + 1 addr byte. Found in GD5GxGQ4xA/E 3. opcode + 1 dummy byte. Found in other currently supported chips. Original implementation was for variant 1 and let detect function of chips with variant 2 and 3 to ignore the first byte. This isn't robust: 1. For chips of variant 2, if SPI master doesn't keep MOSI low during read, chip will get a random id offset, and the entire id buffer will shift by that offset, causing detect failure. 2. For chips of variant 1, if it happens to get a devid that equals to manufacture id of variant 2 or 3 chips, it'll get incorrectly detected. This patch reworks detect procedure to address problems above. New logic do detection for all variants separatedly, in 1-2-3 order. Since all current detect methods do exactly the same id matching procedure, unify them into core.c and remove detect method from manufacture_ops.
