    1280x1024 and 1024x768 @ 32 bpp are supported now.
    DVI, Single-link LVDS, Double-link LVDS are all supported.
    
    Environmental variable "monitor" is used to specify monitor port.
    
    A new command "diufb" is introduced to reinitialize monitor
    and display a BMP file in the memory. So far, 1-bit, 4-bit,
    8-bit and 24-bit BMP formats are supported.
    
        diufb init
            - initialize the diu driver
        Enable the port specified in the environmental variable "monitor"
    
        diufb addr
            - display bmp file in memory.
        The bmp image should be no bigger than the resolution, 1280x1024
        for DVI and double-link LVDS, 1024x768 for single-link LVDS.
    
    Note, this driver allocate memory but doesn't free it after use
    It is written on purpose -- to avoid a failure of reallocation
    due to memory fragement.
    
    ECC of DDR is disabled for DIU performance. L2 data cache is also disabled.
