    imgvp-danube: Support for the ImgTec Danube Virtual Platform
    
    Add basic board support for the ImgTec Danube Virtual Platform, which
    emulates a system built around the Danube SoC.
    
    Run this by loading coreboot.bimg into a flash device connected to SPFI1
    chip select 0 & then executing the Danube boot ROM.
