kirkwood: add support for D-Link DNS-325 A1

The D-Link DNS-325 A1 is NAS with 2x HDD (3.5 inch) bays, 1x 10/100/1000Base-T port and 1x USB 2.0 port

Device specification:

    SoC: Marvell 88F6281-A1 1.2 GHz
    RAM: 256 MB (2xSEC K4T1G084QF-HCF7:128Mx8 @400 CL6)
    Flash: 128 MB (SAMSUNG 946 K9F1G08U0B PCB0)
    SATA: 2x internal SATA II drives
    Ethernet: 1x Gigabit (Marvell 88E1116R-NNC1)
    LED: 7x (white: Power, white/red: Right SATA Activity, USB Activity, Left SATA Activity)
    Key: 3x (Power, Reset, USB Copy/Unmount)
    Serial: 5 pin header (RXD,GAP,3.3V,GND,TXD), (115200,8,N,1), 3.3V TTL
    USB ports: 1x USB 2.0

Flash instruction:

NOTE: this process uses a serial connection. It will upgrade the bootloader and reset the bootloader environment variables

USB flash stick setup

    Format to FAT32 without mbr
    Copy these files to USB flash stick: dlink_dns-325-a1-initramfs-uImage dlink_dns-325-a1-squashfs-factory.bin dlink_dns-325-a1-squashfs-sysupgrade.bin u-boot.kwb (from u-boot-dns325 directory)

NAS setup

    Connect LAN cable between router and NAS device
    Connetc USB flash stick to NAS device
    Connect serial to NAS device

Boot from new u-boot and install it

    $ kwboot -p -b u-boot.kwb -B115200 -t /dev/ttyUSB0
    Power on NAS
    After download copleted and booted NAS device with new u-boot stop in bootloader by pressing any key
    => usb start
    => fatload usb 0 0x1000000 /u-boot.kwb
    => nand erase.part u-boot
    => nand write 0x1000000 u-boot ${filesize}
    => reset

Update MAC address in u-boot env

    Stop in bootloader by pressing any key
    Get your MAC address from label on chassis
    => setenv ethaddr XX:XX:XX:XX:XX:XX
    => saveenv

Install OpenWrt by flashing factory image from u-boot

    => usb start
    => fatload usb 0 0x1000000 /dlink_dns-325-a1-squashfs-factory.bin
    => nand erase.part ubi
    => nand write 0x1000000 ubi ${filesize}
    => reset

+Subject: [PATCH] arm: kirkwood: dns325: Correct CONFIG_NR_DRAM_BANKS parameter
+
+Testing on a DNS-325 NAS has shown that in order for the device to work
+we need to set CONFIG_NR_DRAM_BANKS to 1 and not 2.
