[RFT 4/5] realtek: support D-Link DGS-1210-10P H/W:R1

[Paul Fertser]

This is an 8 port 1000BASE-T + 2 1000BASE-X SFP gigabit switch with PoE+
support, 65 W budget (using 54 V * 1.574 A = 85 W power supply).

In order to manipulate the PoE+ one needs the realtek-poe package [0].

Specifications
--------------
* SoC:       Realtek RTL8380M 500 MHz MIPS 4KEc
* Flash:     Macronix MX25L25645GMI-08G 32 MiB
* RAM:       Nanya NT5CC256M8JQ-EK 256 MiB DDR3(L) SDRAM
* Ethernet:  8x 10/100/1000 1000BASE-T
             2x 1000BASE-X SFP
* PoE+:      Broadcom BCM59121B0KMLG (IEEE 802.3at-2009 compliant)
             Controlled by Nuvoton M0516LDE MCU talking undocumented
             protocol to the Realtek's second UART
* Buttons:   Mode ("lights_toggle") and Reset
* LEDs:      Power, PoE Max, Link and PoE software-controlled; per-port
             link indication LEDs hardware-controlled
* UART:      2.54 mm header with populated standard pin connector J8
             Pin 1: Vcc (3.3 V)
             Pin 2: Tx
             Pin 3: Rx
             Pin 4: GND
             Baud and framing: 115200 8n1

Installation
------------

* Configure your client with static 10.90.90.91/24 address.
* Set up a TFTP server on your client and make it serve the initramfs
  image. Connect it to port 1 of the switch.
* Connect serial, power up the switch, interrupt U-boot by hitting
  Escape after seeing "Power on self test" message
* Download the image onto the device and boot from it:
  > tftpboot 0x8f000000 10.90.90.91:openwrt-realtek-generic-d-link_dgs-1210-10p-r1-initramfs-kernel.bin
  > bootm
* Once OpenWrt has booted reconfigure your client to use VID 100 and DHCP,
  scp the sysupgrade image to /tmp and run sysupgrade.
