2 * linux/drivers/video/atafb.c -- Atari builtin chipset frame buffer device
11 * - 03 Jan 95: Original version by Martin Schaller: The TT driver and
13 * - 09 Jan 95: Roman: I've added the hardware abstraction (hw_switch)
16 * - 07 May 95: Martin: Added colormap operations for the external driver
17 * - 21 May 95: Martin: Added support for overscan
19 * - Jul 95: Guenther Kelleter <guenther@pool.informatik.rwth-aachen.de>:
23 * - 27 Dec 95: Guenther: Implemented user definable video modes "user[0-7]"
28 * - 23 Sep 97: Juergen: added xres_virtual for cards like ProMST
29 * The external-part is legacy, therefore hardware-specific
32 * - 29 Sep 97: Juergen: added Romans suggestion for pan_display
33 * (var->xoffset was changed even if no set_screen_base avail.)
34 * - 05 Oct 97: Juergen: extfb (PACKED_PIXEL) is FB_PSEUDOCOLOR 'cause
40 * - For the Falcon it is not possible to set random video modes on
