Mostly working, lacking LED initialization changes. LEDs will be added later once #107 is merged. Closes #76.

Following is documentation for unmanaged switch marked as TEG-S563/EU H/W: V1.0R.
Original software is running UART on 57600 baud rate. The software does not allow to
do anything fancy via serial. There is IP configuration which can be printed as well.
There might be also some flash upload procedure, but using SPI clamp in-board seems to
be easier method.
The memory chip is Winbond W25Q16JV with 16M-bit size.
What does work
- 2.5G ports on all advertised speeds.
- SFP+ communication.
- Serial, Web UI.
Known issues
- LEDs are not initialized properly.

SW1 GPIO switch?
Not populated but looks like a switch for selecting GPIO level. Missing resistors in place.
GPIO mapping unknown.
S2 Reset ciruit
Not populated but looks like a button can be added on S2 connector,
requires additional R571 resistor which will pull signal to ground.
GPIO mapping unknown.

LEDs
Leds are not yet working as in stock firmware. This will be handled later.
Ports 1-4 are amber for 100M/1G links, Green for 2.5G. Port 5-6 are green for 10G/1G link. Both should flash on activity.

Power supply
Input power is delivered via barell plug, 12V 1A adapter was provided.
Board has two supply rails. 0.95 and 3.3 volt.
0.95 Core Voltage
Voltage is made by a APW8713 (U3).
3.3 Voltage
Voltage is crated regulated by chip marke as GoIAT (U2).
SFP SPI
There is separate clock and data lines for both SFP modules. MSDA/MSCK 0 and 1 need to be enabled.
SFP1 slot is connected to SPI0. SFP2 slot is connected to SPI1.
