commit 63763345d94b11f106c832c23e8ad730a4485723
Author: Mariano Alvira <ma...@de...>
Date:   Sat Feb 27 22:52:34 2010 -0800

    add board/redbee-econotag.cfg and JTAG support
    
    The Redbee Econotag is an open hardware development kit from
    Redwire, LLC (www.redwirellc.com/store), for the Freescale
    MC13224V ARM7TDMI + 802.15.4 radio.
    
    It includes both an MC13224V and an FT2232H (for JTAG and UART
    support).  It has flexible power supply options.
    
    Additional features are:
    
      - inverted-F pcb antenna
      - 36 GPIO brought out to 0.1" pin header
        (includes all peripheral pins)
      - Reset button
      - Two push buttons (on kbi1-5 and kbi0-4)
      - USB-A connector, powered from USB
      - up to 16V external input
      - pads for optional buck inductor
      - pads for optional 32.768kHz crystal
      - 2x LEDS on TX_ON and RX_ON

commit e4a40d257d6c8fa393929cda50c0a1d777787da2

    Add target/mc13224v.cfg
    
    The MC13224V is a FreeScale ARM7TDMI based IEEE802.15.4 platform for
    Zigbee and similar low-power wireless applications. Using PIP
    (Platform In Package) technology, it integrates: an RF balun and
    matching network; a buck converter (only an external inductor is
    necessary); 96KB of SRAM; and 128KB of non-volatile memory.
    
    It has an integrated bootloader and can boot from a variety of sources:
    external SPI or I2C non-volatile memory, an image loaded over UART1,
    or the internal non-volatile memory. The image loaded from one of these
    sources is executed directly from SRAM starting at location 0x00400000.
