    mvebu: add support for Buffalo LinkStation LS220DE
    
    The Buffalo LinkStation LS220DE is a dual bay NAS, based on Marvell
    Armada 370
    
    Hardware:
       SoC:         Marvell Armada 88F6707
       CPU:         Cortex-A9 800 MHz, 1 core
       Flash 1:     SPI-NOR 1 MiB (U-Boot)
       Flash 2:     NAND 512 MiB (OS)
       RAM:         DDR3 256 MiB
       Ethernet:    1x 1GbE
       USB:         1x 2.0
       SATA:        2x 3Gb/s
       LEDs/Input:  5x / 2x (1x button, 1x slide-switch)
       Fan:         1x casing
    
    Flash instructions, from hard drive:
      1. Get access to the "boot" partition at the hard drive where the stock
         firmware is installed. It can be done with acp-commander or by
         plugging the hard drive to a computer.
      2. Backup the stock uImage:
             mv /boot/uImage.buffalo /boot/uImage.buffalo.bak
      3. Move and rename the Openwrt initramfs image to the boot partition:
             mv openwrt-initramfs-kernel.bin /boot/uImage.buffalo
      4. Power on the Linkstation with the hardrive inside. Now Openwrt will
         boot, but still not installed.
      5. Connect via ssh to OpenWrt:
             ssh root at 192.168.1.1
      6. Rename boot files inside boot partition
             mount -t ext3 /dev/sda1 /mnt
             mv /mnt/uImage.buffalo /mnt/uImage.buffalo.openwrt.bak
             mv /mnt/initrd.buffalo /mnt/initrd.buffalo.bak
      7. Format ubi partitions at the NAND flash ("kernel_ubi" and "ubi"):
             ubiformat /dev/mtd0 -y
             ubidetach -p /dev/mtd1
             ubiformat /dev/mtd1 -y
      8. Flash the sysupgrade image:
             sysupgrade -n openwrt-squashfs-sysupgrade.bin
      9. Wait until it finish, the device will reboot with OpenWrt installed
         on the NAND flash.
    
    Restore the stock firmware:
      1. Take the hard drive used for the installation and restore boot backup
         files to their original names:
             mount -t ext3 /dev/sda1 /mnt
             mv /mnt/uImage.buffalo.bak /mnt/uImage.buffalo
             mv /mnt/initrd.buffalo.bak /mnt/initrd.buffalo
      2. Boot from the hard drive and perform a stock firmware update using
         the Buffalo utility. The NAND will be restored to the original
         state.
