    ramips: add support for D-Link Dir-853 A1
    
    Specifications:
    * SoC: MT7621AT
    * RAM: 256MB (NT5CC64M16GP-DI)
    * Flash: 16MB NOR SPI flash (GD25Q127CSIG, using GD25Q128C driver)
    * WiFi: MT7615DN (2.4GHz+5Ghz) with DBDC
    * Ethernet: 4x1000M LAN, 1x 1000M WAN
    * LEDs: Power Blue+Orange,Wan Blue+Orange,WPS Blue,"2.4G"Blue, "5G" Blue,
      USB Blue
    * Buttons: Reset,WPS, Wifi
    * Serial interface: on board but not populated, pinout (from the DC jack
    side to the WAN port side) is "3.3V Input Output Gnd". Baud rate is 57600,
    settings are 8 data bits, no parity bit, one stop bit, and no flow control.
    
    Stock flash layout:
    ```
    GD25Q128C(c8 40180000) (16384 Kbytes)
    mtd .name = raspi, .size = 0x01000000 (16M) .erasesize = 0x00010000 (64K)
    .numeraseregions = 0
    Creating 7 MTD partitions on "raspi":
    0x000000000000-0x000001000000 : "ALL"
    0x000000000000-0x000000030000 : "Bootloader"
    0x000000030000-0x000000040000 : "Config"
    0x000000040000-0x000000050000 : "Factory"
    0x000000050000-0x000000060000 : "Config2"
    0x000000060000-0x000000fb0000 : "Kernel"
    0x000000fb0000-0x000001000000 : "Private"
    ```
    The kernel partition will be replaced with the OpenWrt image, the other
    partitions are left untouched.
    
    "Config2" seems to be the config storage used by the stock firmware.
    
    "Private" is a 320kB empty JFFS2 partition that comes with the stock
    firmware. One can get a larger space for OpenWrt by merging it with
    "Kernel".
    
    OpenWrt flash layout:
    ```
    0x000000000000-0x000000030000 : "u-boot"
    0x000000030000-0x000000040000 : "u-boot-env"
    0x000000040000-0x000000050000 : "factory"
    0x000000050000-0x000000060000 : "config2_stock"
    0x000000060000-0x000000fb0000 : "firmware"
    0x000000fb0000-0x000001000000 : "private_stock"
    ```
    
    The OpenWrt image must have 96 bytes of padding in the header.
    
    MAC addresses on OEM firmware:
    |               | location on the flash         | notes         |
    |------         |-----------------------        |----------     |
    | lan (eth2)    | factory + 0xe000              | on label      |
    | wan (eth3)    | factory + 0xe006              |               |
    | 2.4g (rax0)   | not on flash                  | lan + 1       |
    | 5g (ra0)      | not on flash                  | lan + 2       |
    
    Mac addresses of the 2.4g and 5g interface are stored as ASCII strings in
    the u-boot-env partition, but they are not used. OpenWrt calculates
    Wifi Mac addresses based on the LAN Mac.
    
    Flash and test instructions:
    Flash the encrypted image (available in the OpenWrt forum) through the
    stock D-Dink web interface.
    
    1. Open the case, and solder the 4-pin header near the WAN port.
    2. Connect it to a USB-UART TTL (3.3V) adapter, no need to connect VCC.
    3. Open a terminal emulator (e.g. `screen /dev/ttyUSB0` on linux) with
    the settings mentioned above.
    4. Setup a TFTP server on your PC that can serve
    `xxx-ramips-mt7621-dlink_dir-853-a1-initramfs-kernel.bin`.
    5. Connect any LAN port to your PC and set a static IPv4 address to
    192.168.0.101 (netmask 255.255.255.0).
    6. Power on the device and keeps pressing 1 until you see the prompt.
    7. Use default IP addresses and enter the file name accordingly, then hit
    enter.
    8. Wait until it boots to OpenWrt, the default IP address is 192.168.1.1,
    you need to change your PC network adapter to use DHCP in order to access
    LUCI.
    9. So far, the OpenWrt runs in RAM and the flash contents are not touched.
    You can try OpenWrt without having to overwrite the stock firmware, a
    reboot clears all changes.
    10. Optionally, backup the stock firmware (the "firmware" partition) in
    Luci.
    11. To permantly install OpenWrt to the device , click
    on "System -> Backup/Flash Firmware" in Luci and flash
    `xxx-ramips-mt7621-dlink_dir-853-a1-squashfs-sysupgrade.bin`
    
    Known problems:
    * WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network,
    you need to config it manually in LUCI.
    
    * If you see jffs2 related warnings/errors after updating from the stock
    web interface, you need to do a reset in LUCI. The error will be gone after
    a cold reboot.
