|  | 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. |
