[PATCH 0/4] Add WATCHDOG_RESET() in MTD framework and STM32 QSPI driver

[PATCH 0/4] Add WATCHDOG_RESET() in MTD framework and STM32 QSPI driver

[Patrice Chotard]

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()


Patrice Chotard (4):
  mtd: spi-nor: Add WATCHDOG_RESET() in spi_nor_core callbacks
  spi: stm32_qspi: Add WATCHDOG_RESET in _stm32_qspi_read_fifo()
  mtd: nand: Add WATCHDOG_RESET() in nanddev_mtd_erase()
  mtd: spinand: Add WATCHDOG_RESET() in spinand_mtd_read/write()

[PATCH 1/4] mtd: spi-nor: Add WATCHDOG_RESET() in spi_nor_core callbacks

[Patrice Chotard]

In case of big area write/erase on spi nor, watchdog timeout may occurs.
Issue reproduced on stm32mp157c-ev1 with following commands:

sf write 0xC0000000 0 0x3000000
or
sf erase 0 0x1000000

[PATCH 2/4] spi: stm32_qspi: Add WATCHDOG_RESET in _stm32_qspi_read_fifo()

[Patrice Chotard]

In case of reading large area and memory-map mode is misconfigured
(memory-map size declared lower than the real size of the memory chip)
watchdog can be triggered.

Add WATCHDOG_RESET() in _stm32_qspi_read_fifo to fix it.

Issue reproduced with stm32mp157c-ev1 board and memory map size set to
1, with following command:
sf read 0xC0000000 0 0x4000000

[PATCH 3/4] mtd: nand: Add WATCHDOG_RESET() in nanddev_mtd_erase()

[Patrice Chotard]

In case of big area erased on nand, watchdog timeout may occurs.
To fix that, add WATCHDOG_RESET() in nanddev_mtd_erase() to ensure that
watchdog is reset.
