    realtek: add support for Panasonic Switch-M8eG PN28080K
    
    Panasonic Switch-M8eG PN28080K is a 8 + 1 port gigabit switch, based on
    RTL8380M.
    
    Specification:
    
    - SoC           : Realtek RTL8380M
    - RAM           : DDR3 128 MiB (Winbond W631GG8KB-15)
    - Flash         : SPI-NOR 32 MiB (Macronix MX25L25635FMI-10G)
    - Ethernet      : 10/100/1000 Mbps x8 + 1
      - port 1-8    : TP, RTL8218B (SoC)
      - port 9      : SFP, RTL8380M (SoC)
    - LEDs/Keys     : 7x / 1x
    - UART          : RS-232 port on the front panel (connector: RJ-45)
      - 3:TX, 4:GND, 5:GND, 6:RX (pin number: RJ-45)
      - 9600n8
    - Power         : 100-240 VAC, 50/60 Hz, 0.5 A
      - Plug        : IEC 60320-C13
    - Stock OS      : VxWorks based
    
    Flash instruction using initramfs image:
    
    1.  Prepare the TFTP server with the IP address 192.168.1.111
    2.  Rename the OpenWrt initramfs image to "0101A8C0.img" and place it to
        the TFTP directory
    3.  Download the official upgrading firmware (ex: pn28080k_v30000.rom)
        and place it to the TFTP directory
    4.  Boot M8eG and interrupt the U-Boot with Ctrl + C keys
    5.  Execute the following commands and boot with the OpenWrt initramfs
        image
    
        rtk network on
        tftpboot 0x81000000
        bootm
    
    6.  Backup mtdblock files to the computer by scp or anything and reboot
    7.  Interrupt the U-Boot and execute the following commands to re-create
        filesystem in the flash
    
        ffsmount c:/
        ffsfmt c:/
    
        this step takes a long time, about ~ 4 mins
    
    8.  Execute the following commands to put the official images to the
        filesystem
    
        updatert <official image>
    
        example:
    
          updatert pn28080k_v30000.rom
    
        this step takes about ~ 40 secs
    
    9.  Set the environment variables of the U-Boot by the following commands
    
        setenv loadaddr 0xb4e00000
        setenv bootcmd bootm
        saveenv
    
    10: Download the OpenWrt initramfs image and boot with it
    
        tftpboot 0x81000000 0101A8C0.img
        bootm
    
    11: On the initramfs image, download the sysupgrade image and perform
        sysupgrade with it
    
        sysupgrade <imagename>
    
    12: Wait ~ 120 seconds to complete flashing
    
    Note:
    
    - "Switch-M8eG" is a model name, and "PN28080K" is a model number.
      Switch-M8eG has an another (old) model number ("PN28080"), it's not a
      Realtek based hardware.
    
    - Switch-M8eG has a "POWER" LED (Green), but it's not connected to any
      GPIO pin.
    
    - The U-Boot checks the runtime images in the flash when booting and
      fails to execute anything in "bootcmd" variable if the images are not
      exsisting.
    
    - A filesystem is formed in the flash (0x100000-0x1DFFFFF) on the stock
      firmware and it includes the stock images, configuration files and
      checksum files. It's unknown format, can't be managed on the OpenWrt.
      To get the enough space for OpenWrt, move the filesystem to the head
      of "fs_reserved" partition by execution of "ffsfmt" and "updatert".
    
    - On the other devices in the same series of Switch-M8eG PN28080K, the
      INT pin on the PCA9555 is not connected to anywhere.
    
    Back to the stock firmware:
    
    1. Delete "loadaddr" variable and set "bootcmd" to the original value
    
       on U-Boot:
    
         setenv loadaddr
         setenv bootcmd 'bootm 0x81000000'
    
       on OpenWrt:
    
         fw_setenv loadaddr
         fw_setenv bootcmd 'bootm 0x81000000'
    
    2. Perform reset or reboot
    
      on U-Boot:
    
        reset
    
      on OpenWrt:
    
        reboot
