    VRFB rotation engine is a block in OMAP2/3 that offers 12 independent
    contexts that can be used for framebuffer rotation.
    
    Each context has a backend area of real memory, where it stores the
    pixels in undisclosed format. This memory is offered to users via 4
    virtual memory areas, which see the same memory area in different
    rotation angles (0, 90, 180 and 270 degrees).
