9description:
10  Chrom-ART Accelerator(DMA2D), graphical hardware accelerator
11  enabling enhanced graphical user interface with minimum CPU load
12
13  It can perform the following operations.
14
15  - Filling a part or the whole of a destination image with a specific color.
16  - Copying a part or the whole of a source image into a part or the whole of
17    a destination image.
18  - Copying a part or the whole of a source image into a part or the whole of
19    a destination image with a pixel format conversion.
20  - Blending a part and/or two complete source images with different pixel
21    format and copy the result into a part or the whole of a destination image
22    with a different color format. (TODO)
