// When BIOS flash happened, before erase/write BIOS should notify EC to set flag (WdtFlag should be
|
|
// keeped even EC power lost, such as stored in the EC EEPROM) to enable WDT, the WdtFlag should be
|
|
// cleared when EC received BIOS "cancel WDT" command.

|
// On every boot, EC check the WdtFlag flag to decide if need to start a 15s WDT,
|
|
// and stop the WDT if BIOS send "stop/cancel WDT" command.
