- Watchdog driver general info
- CONFIG_HW_WATCHDOG
- This enables hw_watchdog_reset to be called during various loops,
- including waiting for a character on a serial port. But it
- does not also call hw_watchdog_init. Boards which want this
- enabled must call this function in their board file. This split
- is useful because some rom's enable the watchdog when downloading
- new code, so it must be serviced, but the board would rather it
- was off. And, it cannot always be turned off once on.
- CONFIG_WATCHDOG_TIMEOUT_MSECS
- Can be used to change the timeout for i.mx31/35/5x/6x.
- If not given, will default to maximum timeout. This would
- be 128000 msec for i.mx31/35/5x/6x.
- CONFIG_AT91SAM9_WATCHDOG
- Available for AT91SAM9 to service the watchdog.
- CONFIG_FTWDT010_WATCHDOG
- Available for FTWDT010 to service the watchdog.
- CONFIG_FTWDT010_HW_TIMEOUT
- Can be used to change the timeout for FTWDT010.
- CONFIG_IMX_WATCHDOG
- Available for i.mx31/35/5x/6x to service the watchdog. This is not
- automatically set because some boards (vision2) still need to define
- their own hw_watchdog_reset routine.
- TODO: vision2 is removed now, so perhaps this can be changed.
- CONFIG_XILINX_TB_WATCHDOG
- Available for Xilinx Axi platforms to service timebase watchdog timer.
- CONFIG_BFIN_WATCHDOG
- Available for bf5xx and bf6xx to service the watchdog.
