    ath79: add support for Teltonika RUT230 v1
    
    This commit adds support for the Teltonika RUT230 v1, a Atheros AR9331
    based router with a Quectel UC20 UMTS modem.
    
    Hardware
    --------
    Atheros AR9331
    16 MB SPI-NOR XTX XT25F128B
    64M DDR2 memory
    Atheros AR9331 1T1R 802.11bgn Wireless
    Boootloader: pepe2k U-Boot mod
    
    Hardware-Revision
    -----------------
    There are two board revisions of the RUT230, a v0 and v1.
    
    A HW version is silkscreened on the top of the PCBs front side as well
    as shown in the Teltonika UI. However, this looks to be a different
    identifier, as the GPl dump shows this silkscreened / UI shown version
    are internally treated identically.
    
    Th following mapping has been obtained from the latest GPl dump.
    
    HW Ver   01 - 04 --> v0
    HW Ver > 05      --> v1
    
    My board was a HW Ver 09 and is treated as a v1.
    
    Installation
    ------------
    While attaching power, hold down the reset button and release it after
    the signal LEDs flashed 3 times.
    
    Attach your Computer with the devices LAN port and assign yourself the
    IPv4 address 192.168.1.10/24. Open a web browser, navigate to
    192.168.1.1. Upload the OpenWrt factory image.
    
    The device will install OpenWrt and automatically reboots afterwards.
    
    You can use the smae procedure with the stock firmware to return back to
    the vendor firmware.
