    bcm53xx: enhance support for Linksys EA9500
    
    1. Add leds and configs
    2. Add network configs
    3. Add script to clear partial boot flag
    4. Hack to use port 5 as cpu port as port 8 connected to eth2
       wont pass any frames
    5. Enable EA9500 image generation
    
    Hardware Info:
    
    - Processor - Broadcom BCM4709C0KFEBG dual-core @ 1.4 GHz
    - Switch - BCM53012 in BCM4709C0KFEBG & external BCM53125
    - DDR3 RAM - 256 MB
    - Flash - 128 MB (Toshiba TC58BVG0S3HTA00)
    - 2.4GHz - BCM4366 4×4 2.4/5G single chip 802.11ac SoC
    - Power Amp - Skyworks SE2623L 2.4 GHz power amp (x4)
    - 5GHz x 2 - BCM4366 4×4 2.4/5G single chip 802.11ac SoC
    - Power Amp - PLX Technology PEX8603 3-lane, 3-port PCIe switch
    - Ports - 8 Ports, 1 WAN Ports
    - Antennas - 8 Antennas
    - Serial Port - @j6 [GND,TX,RX] (VCC NC) 115200 8n1
    
    Flashing Instructions:
    
    1. Connect a USB-TTL table to J6 on the router as well as a
       ethernet cable to a lan port and your PC.
    2. Power-on the router.
    3. Use putty or a serial port program to view the terminal.
       Hit Ctrl+C and interrupt the CFE terminal terminal.
    4. Setup a TFTP server on your local machine at setup you
       local IP to 192.168.1.2
    5. Start the TFTP Server
    6. Run following commands at the CFE terminal
    
       flash -noheader 192.168.1.2:/openwrt.trx nflash0.trx
       flash -noheader 192.168.1.2:/openwrt.trx nflash0.trx2
       nvram set bootpartition=0 && nvram set partialboots=0 && nvram commit
    
    7. Reboot router to be presented by OpenWrt
    
    Note: Only installation method via serial cable is supported at the moment.
    The trx firmware has to be flashed to both the partitions using following
    commands from CFE prompt. This will cover US and Non-US variants.
