+/* suncons.c: Sun SparcStation console support.
+ *
+ * Copyright (C) 1995 Peter Zaitcev (zaitcev@lab.ipmce.su)
+ * Copyright (C) 1995 David S. Miller (davem@caip.rutgers.edu)
+ * Copyright (C) 1995 Miguel de Icaza (miguel@nuclecu.unam.mx)
+ *
+ * Added font loading Nov/21, Miguel de Icaza (miguel@nuclecu.unam.mx)
+ * Added render_screen and faster scrolling Nov/27, miguel
+ * Added console palette code for cg6 Dec/13/95, miguel
+ * Added generic frame buffer support Dec/14/95, miguel
+ * Added cgsix and bwtwo drivers Jan/96, miguel
+ * Added 4m, and cg3 driver Feb/96, miguel
+ * Fixed the cursor on color displays Feb/96, miguel.
+ *
+ * Cleaned up the detection code, generic 8bit depth display
+ * code, Mar/96 miguel
+ *
+ * This file contains the frame buffer device drivers.
+ * Each driver is kept together in case we would like to
+ * split this file.
+ *
+ * Much of this driver is derived from the DEC TGA driver by
+ * Jay Estabrook who has done a nice job with the console
+ * driver abstraction btw.
+ *
+ * We try to make everything a power of two if possible to
+ * speed up the bit blit. Doing multiplies, divides, and
+ * remainer routines end up calling software library routines
+ * since not all Sparcs have the hardware to do it.
+ *
+ * TODO:
+ * do not use minor to index into instances of the frame buffer,
+ * since the numbers assigned to us are not consecutive.
+ *
+ * do not blank the screen when frame buffer is mapped.
+ *
+ * Change the detection loop to use more than one video card.
