|
|
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.
