3CONFIG_HW_WATCHDOG
4 This enables hw_watchdog_reset to be called during various loops,
5 including waiting for a character on a serial port. But it
6 does not also call hw_watchdog_init. Boards which want this
7 enabled must call this function in their board file. This split
8 is useful because some rom's enable the watchdog when downloading
9 new code, so it must be serviced, but the board would rather it
10 was off. And, it cannot always be turned off once on.

12CONFIG_WATCHDOG_TIMEOUT_MSECS
13 Can be used to change the timeout for i.mx31/35/5x/6x.
14 If not given, will default to maximum timeout. This would
15 be 128000 msec for i.mx31/35/5x/6x.

Troy Kiskyabbab702012-10-22 15:19:01 +000018 Available for AT91SAM9 to service the watchdog.

Troy Kiskyabbab702012-10-22 15:19:01 +000020CONFIG_IMX_WATCHDOG
21 Available for i.mx31/35/5x/6x to service the watchdog. This is not
22 automatically set because some boards (vision2) still need to define
23 their own hw_watchdog_reset routine.
Simon Glassbee2b992015-08-30 19:19:31 -060024 TODO: vision2 is removed now, so perhaps this can be changed.
