    realtek: add support for ZyXEL GS1900-8HP v1 and v2
    
    The ZyXEL GS1900-8HP is an 8 port gigabit switch with PoE+ support.
    There are two versions on the market (v1 & v2) which share similar
    specs (same flash size and flash layout, same RAM size, same PoE+ power
    envelope) but have a different case and board layout that they each
    share with other GS1900 siblings.
    
    The v1 seems to share its PCB and case with non-PoE GS1900-8; as such,
    adding support for the GS1900-8 would probably be trivial. The v2 seems
    to share its casing and platform with its already supported bigger
    brother, the GS1900-10HP - its board looks the same, except for two
    holes where the GS1900-10 has its SFP ports.
    
    Like their 10 port sibling, both devices have a dual firmware layout.
    Both GS1900-8HP boards have the same 70W PoE+ power budget. In order to
    manipulate the PoE+, one needs the rtl83xx-poe package [1].
    
    After careful consideration it was decided to go with separate images
    for each version.
    
    Specifications (v1)
    -------------------
    * SoC:       Realtek RTL8380M 500 MHz MIPS 4KEc
    * Flash:     Macronix MX25L12835F 16 MiB
    * RAM:       Nanya NT5TU128M8HE-AC 128 MiB DDR2 SDRAM
    * Ethernet:  8x 10/100/1000 Mbit
    * PoE+:      Broadcom BCM59111KMLG (IEEE 802.3at-2009 compliant, 2x)
    * UART:      1 serial header with populated standard pin connector on the
                 left side of the PCB, towards the bottom. Pins are labeled:
                 + VCC (3.3V)
                 + TX
                 + RX
                 + GND
    
    Specifications (v2)
    -------------------
    * SoC:       Realtek RTL8380M 500 MHz MIPS 4KEc
    * Flash:     Macronix MX25L12835F 16 MiB
    * RAM:       Samsung K4B1G0846G 128 MiB DDR3 SDRAM
    * Ethernet:  8x 10/100/1000 Mbit
    * PoE+:      Broadcom BCM59121B0KMLG (IEEE 802.3at-2009 compliant)
    * UART:      1 angled serial header with populated standard pin connector
                 accessible from outside through the ventilation slits on the
                 side. Pins from top to bottom are clearly marked on the PCB:
                 + VCC (3.3V)
                 + TX
                 + RX
                 + GND
    
    Serial connection parameters for both devices: 115200 8N1.
    
    Installation
    ------------
    Instructions are identical to those for the GS1900-10HP and apply both
    to the GS1900-8HP v1 and v2 as well.
    
    * Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
    * Set up a TFTP server on your client and make it serve the initramfs
      image.
    * Connect serial, power up the switch, interrupt U-boot by hitting the
      space bar, and enable the network:
      > rtk network on
    * Since the GS1900-10HP is a dual-partition device, you want to keep the
      OEM firmware on the backup partition for the time being. OpenWrt can
      only boot off the first partition anyway (hardcoded in the DTS). To
      make sure we are manipulating the first partition, issue the following
      commands:
      > setsys bootpartition 0
      > savesys
    * Download the image onto the device and boot from it:
      > tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-8hp-v{1,2}-initramfs-kernel.bin
      > bootm
    * Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
      > sysupgrade /tmp//tmp/openwrt-realtek-generic-zyxel_gs1900-8hp-v{1,2}-squashfs-sysupgrade.bin
