In case of large area read/write/erase on spi nor and spi nand, watchdog may occurs depending on watchdog timeout and MTD device size. Some of these use-cases has been reproduced with stm32mp157-ev1 board.
To prevent this situation, WATHDOG_RESET() are added at several location: - Add WATCHDOG_RESET() in spi_nor_erase() and spi_nor_write() - Add WATCHDOG_RESET() in _stm32_qspi_read_fifo() - Add WATCHDOG_RESET() in nanddev_mtd_erase() - Add WATCHDOG_RESET() in spinand_mtd_read() and spinand_mtd_erase()
