This pull request adds basic support for the minispartan6+ board. The following features work;

  • BaseSoC with support for;
    • SDRAM
    • SPI Flash
    • Serial UART
    • Loading firmware from SPI flash (as FPGA doesn't have enough blockram for embedded ROM).
  • VideoMixerSoC with support for;
    • HDMI Output on J3
    • Potentially HDMI input, but no way to test.
    • It does not currently support both HDMI input and output at the same time. See #255 for the reasons.

This support is pretty comparable to the current pipistrello support and should be enough for some basic development and testing.

minispartan6: Enable DDR status.
While the minispartan6 only has SDRAM, we'll call it DDR so it can share code.
