The Galaxy Tab and Galaxy Tab 2 tablets have a custom 30 pin connector.
The goal is to get access to the SOC UART to interact with the bootloader, get kernel boot logs, etc.
To make it easier we want to reuse existing cables without much modifications to the cables.
While this is being tested on the Galaxy Tab 2, it should also work on the Galaxy Tab.

Exported pins: USB D+, USB D-, USB VCC, USB GND, UART RX, UART TX. The ID pin isn't exported.
The USB cable can be plugged in a regular computer.
The RX and TX and GND are exported on the RJ45 cable.
With the clip on the bottom, we have:

TODO: Test RX and TX, to what are they exported? The modem? The SOC?
