J4 connector

I was unsure what this connector was used for but Tommy Sools noticed the following log message from Release.Log found in the Linksys GPL source package:

        CVS TAG:        R20030613_V1103
V11.03  2003/06/13      (AMD V10.04)
        1) Vincent Chen changes Specs.:
        NTSC/PAL switching is hard-coded. The F/W will not check the
        jumper to do the NTSC/PAL switch. (The jumper is useless.)"

It seems likely the connector was in fact intended to be a jumper to select between NTSC and PAL video output formats.

The connections are as follows:

Pin	Function
1	GND
2	GPIO 10
3	High impedance VDD (3.3v through a 4.7k resistor)

Pin 1 is closest to LEDs

The GPIO can be configured as an input or output and, unlike some other GPIO pins, has no alternate functions.
