Hi, This series proposes patches for adding the following functionality in SPI NAND core: - Octal DTR SPI (8D-8D-8D) mode support - Winbond W35N01JW SPI NAND chip support - Power-on-Reset instruction support This series has been tested on TI J721e EVM with the Winbond W35N01JW flash with following test utilities: - nandtest Test log: https://textbin.net/raw/fhypoz63f9 - mtd_stresstest Test log: https://textbin.net/raw/0xqjmqntj7 - UBIFS LTP stress test (NAND_XL_STRESS_DD_RW_UBIFS).
