Julian Oes 7e46d282eb drivers/mtd: Add W25N SPI NAND flash driver ... Add MTD driver for Winbond W25N series SPI NAND flash. Currently supports W25N01GV (1Gbit/128MB). Features: - Standard SPI interface with configurable frequency (up to 104 MHz) - Hardware ECC enabled by default - Block erase with sleep-based wait (releases SPI bus) - Page read/write with busy-wait for fast operations Limitations: - No bad block management (BBM). Factory bad blocks and runtime bad blocks are not tracked. - No bad block table (BBT) scanning at initialization. - No Quad SPI support (standard SPI only). - No access to spare area (64 bytes/page) or OTP region. Tested using: - Board with STM32H743 - W25N01GV on SPI at 96 MHz with DMA enabled - Flash mounted using littlefs - Tested using sdbench: - Sequential write speed of 1760 KB/s - Sequential read speed of 4900 KB/s Signed-off-by: Julian Oes <julian@oes.ch>		2025-12-19 10:00:33 +08:00
