This commit makes the interrupt WDT API private. To use the API, IDF components should now '#include "esp_private/esp_int_wdt.h"'

This routine enables a watchdog to catch instances of processes disabling
|
|
interrupts for too long, or code within interrupt handlers taking too long.
|
|
It does this by setting up a watchdog which gets fed from the FreeRTOS
|
|
task switch interrupt. When this watchdog times out, initially it will call
|
|
a high-level interrupt routine that will panic FreeRTOS in order to allow
|
|
for forensic examination of the state of the both CPUs. When this interrupt
|
|
handler is not called and the watchdog times out a second time, it will
|
|
reset the SoC.
|
|
|
|
This uses the TIMERG1 WDT.
