[ Upstream commit ef569d5db50e7edd709e482157769a5b3c367e22 ]
The external output reset signal was originally disabled and sent from firmware. However, an unfixed bug in the firmware on tomato prevents the signal from being sent, causing the device to fail to boot. To fix this, enable external output reset signal to allow the device to reboot normally.
