mtd: spi: Set CONFIG_SF_DEFAULT_MODE default to 0

2021-09-28T16:03:21+00:00

Before e2e95e5e254 ("spi: Update speed/mode on change") most systems silently defaulted to SF bus mode 0. Now the mode is always updated, which causes breakage. It seems most SF which are used as boot media operate in bus mode 0, so switch that as the default. This should fix booting at least on Altera SoCFPGA, ST STM32, Xilinx ZynqMP, NXP iMX and Rockchip SoCs, which recently ran into trouble with mode 3. Marvell Kirkwood and Xilinx microblaze need to be checked as those might need mode 3.

mtd: spi: nor: force mtd name to "nor%d"

2021-09-28T16:03:20+00:00

Force the mtd name of spi-nor to "nor" + the driver sequence number: "nor0", "nor1"... beginning after the existing nor devices. This patch is coherent with existing "nand" and "spi-nand" mtd device names. When CFI MTD NOR device are supported, the spi-nor index is chosen after the last CFI device defined by CONFIG_SYS_MAX_FLASH_BANKS. When CONFIG_SYS_MAX_FLASH_BANKS_DETECT is activated, this config is replaced by to cfi_flash_num_flash_banks in the include file mtd/cfi_flash.h. This generic name "nor%d" can be use to identify the mtd spi-nor device without knowing the real device name or the DT path of the device, used with API get_mtd_device_nm() and is used in mtdparts command. This patch also avoids issue when the same NOR device is present 2 times, for example on STM32MP15F-EV1: STM32MP> mtd list SF: Detected mx66l51235l with page size 256 Bytes, erase size 64 KiB, \ total 64 MiB List of MTD devices: * nand0 - type: NAND flash - block size: 0x40000 bytes - min I/O: 0x1000 bytes - OOB size: 224 bytes - OOB available: 118 bytes - ECC strength: 8 bits - ECC step size: 512 bytes - bitflip threshold: 6 bits - 0x000000000000-0x000040000000 : "nand0" * mx66l51235l - device: mx66l51235l@0 - parent: spi@58003000 - driver: jedec_spi_nor - path: /soc/spi@58003000/mx66l51235l@0 - type: NOR flash - block size: 0x10000 bytes - min I/O: 0x1 bytes - 0x000000000000-0x000004000000 : "mx66l51235l" * mx66l51235l - device: mx66l51235l@1 - parent: spi@58003000 - driver: jedec_spi_nor - path: /soc/spi@58003000/mx66l51235l@1 - type: NOR flash - block size: 0x10000 bytes - min I/O: 0x1 bytes - 0x000000000000-0x000004000000 : "mx66l51235l" The same mtd name "mx66l51235l" identify the 2 instances mx66l51235l@0 and mx66l51235l@1.

mtd: spi-nor: Mask out fast read if not requested in DT

2021-08-03T06:26:25+00:00

The DT bindings of "jedec,spi-nor" [1] defines "m25p,fast-read" property to indicate that "fast read" opcode can be used to read data from the chip instead of the usual "read" opcode. If this property is not present in DT, mask out fast read in spi_nor_init_params(). This change mirrors the same logic in spi_nor_info_init_params() in drivers/mtd/spi-nor/core.c in the Linux kernel v5.14-rc3.

2021-08-03T06:23:16+00:00

The smart spi_nor_adjust_hwcaps() does not respect the SPI flash's hwcaps, and only looks to the controller on what can be supported. The flash's hwcaps needs to be AND'ed before checking.
