realtek: add support for Linksys LGS328MPCv2 
Hardware specification
----------------------

* RTL9301 SoC, 1 MIPS 34KEc core @ 800MHz
* 512MB DRAM
* 2MB NOR Flash
* 128MB NAND Flash
* 24 x 10/100/1000BASE-T ports with PoE+
* 4 x 10G SFP+ ports
* Power LED, Fault LED, PoE Max LED, LAN Mode LED, PoE Mode LED
* Reset button and LED Mode button on front panel
* LM63 Fan Controller
* UART (115200 8N1) via RJ45
* PSE: Nuvoton M0516LDE via I2C + 3x RTL8238B (not supported yet)

Installation using serial interface
-----------------------------------

1. Press "a" "c" "p" during message "Enter correct key to stop autoboot"
2. Start network "rtk network on"
3. Load image "tftpboot <TFTP IP>:openwrt-realtek-rtl930x_nand-linksys_lgs328mpc-v2-initramfs-kernel.bin"
4. Boot image "bootm"
5. Switch to first bootpartition "fw_setsys bootpartition 0"
6. Download sysupgrade "scp <IP>:openwrt-realtek-rtl930x_nand-linksys_lgs328mpc-v2-squashfs-sysupgrade.bin /tmp/."
7. Install sysupgrade "sysupgrade /tmp/openwrt-realtek-rtl930x_nand-linksys_lgs328mpc-v2-squashfs-sysupgrade.bin"

Installation using OEM webinterface
-----------------------------------

This is not possible because the OpenWrt NAND Flash layout is different
from the vendor layout. To be precise. Vendor uses:

- 64 MB vendor UBI root_data
- 32 MB vendor kernel+root 1 (~19 MB used)
- 32 MB vendor kernel+root 2 (~19 MB used)

OpenWrt uses:

- 64 MB vendor UBI (not touched)
- 10 MB OpenWrt kernel
- 22 MB Openwrt mtd-concat UBI
- 23 MB vendor kernel 2 (space reduced, vendor data unchanged)
- 09 MB OpenWrt mtd-concat UBI

Dual-boot with stock firmware using writable u-boot-env
-------------------------------------------------------

From stock to OpenWrt / primary image 1 (CLI as admin):
   - > boot system image1
   - > reboot

From OpenWrt to stock / boot image 2: (shell as root)
   - # fw_setsys bootpartition 1
   - # reboot

Debrick using serial interface
------------------------------

1. Press "a" "c" "p" during message "Enter correct key to stop autoboot"
2. Load vendor image with "upgrade runtime <TFTP IP>:LGS328xxxxx.imag"
3. switch to primary partition "setsys bootpartition 0"
4. safe config "savesys"

MAC Address Source
------------------

The MAC address for this device is coming from the u-boot-env ethaddr cell.

4439b2ddc2 realtek: add support for D-Link DGS-1250-28X 
Hardware specification
----------------------

* RTL9301 SoC, 1 MIPS 34KEc core @ 800MHz
* 512MB DRAM
* 64MB NAND Flash
* 24 x 10/100/1000BASE-T ports
* 4 x 10G SFP+ ports
* Power LED, Console LED, Fan Fault LED
* Reset button on front panel
* LM75 temperature sensor
* Atmel AT24C02 2kb eeprom
* fan (controllable via gpio for on/off and LM75 for low/high speed)
* UART (115200 8N1) via RJ45

Installation using serial interface
-----------------------------------

 1. Prepare TFTP server & connect to serial port.
 2. Connect DGS-1250 to your computer or network with one of the
    1G ports. All of them will be fine.
 3. Power on DGS-1250 and interrupt autoboot with "&".
 4. Change U-Boot startup sequence
	> setenv silent
	> setenv bootcmd 'cp.l 0xb4200000 0x84000000 0x300000; bootm 0x84000000'
	> saveenv
 5. Enable networking within U-Boot.
	> rtk network on
 6. Set switch IP and TFTP server IP (optional, adjust to your setup).
	> setenv ipaddr <ip>
	> setenv serverip <ip>
 7. Download initramfs image from TFTP server.
	> tftpboot 0x84000000 <image name>
 8. Boot with the downloaded image.
	> bootm 0x84000000
 9. With rambooted OpenWrt, backup the stock firmware.
    THIS IS CRITICAL! /dev/mtd3 contains data that is not provided
    in the downloadable vendor firmware images.
10. Copy sysupgrade image to the device.
11. Perform sysupgrade with the sysupgrade image.
12. After reboot, you should have functional OpenWrt.

Installation using OEM webinterface
-----------------------------------

This is not possible because the vendor image uses a ubifs based
loading technique with encrypted images. To be precise the boot
sequence basically runs as follows.

 1. U-Boot starts
 2. U-Boot mounts 62MB ubifs from mtd3
 3. U-Boot reads Linux kernel from file uImage inside ubifs
 4. Linux starts (this is a initramfs image)
 5. Linux mounts ubifs
 6. Linux calls a loader binary
 7. Depending on current configuration first (file Image1) or
    second firmware image (file Image2) is loaded and decrypted
 8. Inside the decrpyted firmware image there is a executable
    named “switch”
 9. "switch" executable is run and the switch comes alive

Reverting to stock firmware
---------------------------

 1. Boot OpenWrt from initramfs (like in installation section above)
 2. Restore partition /dev/mtd3 from backup
 3. Erase Openwrt special U-Boot env
	# mtd erase mtd1
 4. reboot

ce8ea739eb realtek: rtl931x: Add support for Plasma Cloud ESX28 Switch 
The Plasma Cloud ESX28 Switch is a 24 + 4 port multi-GBit switch with
24x 10/100/1000/2500BaseT Ethernet ports and 4x SFP+ module slot.

Hardware:

- RTL9312C SoC
- Macronix MX25L25645G (32MB flash)
- 512MB DDR3 SDRAM
- RTL8231 GPIO extender to control the port LEDs
- 6x RTL8224 4x 10m/100m/1/2.5 Gigabit PHY
- SFP+ 4x 10GBit slot

The switch is powered directly via AC.

The external RS232 serial connector (RJ45, Cisco pinout) can be used to
access the terminal. Serial connection is via 115200 baud, 8N1.

A reset button is accessible through a hole in the front panel.

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

* The device can be flashed by using sysupgrade command. Either from the
  original vendor firmware or using an initramfs (see "Debug")
* Connect serial on front panel. Connection parameters: 115200 8N1
* The image must be copied using scp to /tmp of the device

      scp openwrt-realtek-rtl931x-plasmacloud_esx28-squashfs-sysupgrade.bin root@[IP address of the device]:/tmp/

* start sysupgrade without saving the original vendor configuration

      sysupgrade -n /tmp/openwrt-realtek-rtl931x-plasmacloud_esx28-squashfs-sysupgrade.bin

Installation via u-boot
-----------------------

If you have an TFTP server connected to the switch, it is possible to
directly install the device using the factory image from u-boot

    # setup networking and IP of TFP server
    rtk network on
    setenv ipaddr 10.100.100.99
    setenv serverip 10.100.100.20

    # get factory image
    tftp 0x84000000 factory.bin

    # erase firmware partitions
    sf probe 0
    sf erase 0x5e0000 0x1a20000

    # write firmware to both partitions
    sf write ${fileaddr} 0x5e0000 ${filesize}
    sf write ${fileaddr} 0x12f0000 ${filesize}

    # adjust the boot commands
    setenv bootargs "mtdparts=spi0.0:768k(u-boot),64k(u-boot-env),64k(u-boot-env2),5120k(reserved),13376k(inactive),13376k(firmware2)"
    setenv bootcmd "rtk init; bootm 0xb52f0000"

    # restart
    reset

Debug
-----

* Connect serial on front panel. Connection parameters: 115200 8N1.
* A tftp server is required, tftpd-hpa works well.
* Power the device, at U-Boot start rapidly hit Esc key to stop autoboot
* Enter passwords: "1234" or "plasmapsx"
* Enable network:

      rtk network on

* Change ip address of device:

      setenv ipaddr 192.168.1.6

* Download initramfs from TFTP server:

      tftpboot 0x84000000 192.168.1.111:openwrt-realtek-rtl931x-plasmacloud_esx28-initramfs-kernel.bin

* Boot loaded file:

      bootm 0x84000000
