/*
* linux/drivers/video/fbcon.c -- Low level frame buffer based console driver
*
* Copyright (C) 1995 Geert Uytterhoeven
*
*
* This file is based on the original Amiga console driver (amicon.c):
*
* Copyright (C) 1993 Hamish Macdonald
* Greg Harp
* Copyright (C) 1994 David Carter [carter@compsci.bristol.ac.uk]
*
* with work by William Rucklidge (wjr@cs.cornell.edu)
* Geert Uytterhoeven
* Jes Sorensen (jds@kom.auc.dk)
* Martin Apel
*
* and on the original Atari console driver (atacon.c):
*
* Copyright (C) 1993 Bjoern Brauel
* Roman Hodek
*
* with work by Guenther Kelleter
* Martin Schaller
* Andreas Schwab
*
* Hardware cursor support added by Emmanuel Marty (core@ggi-project.org)
* Smart redraw scrolling, arbitrary font width support, 512char font support
* and software scrollback added by
* Jakub Jelinek (jj@ultra.linux.cz)
*
* Random hacking by Martin Mares <mj@ucw.cz>
*
* 2001 - Documented with DocBook
* - Brad Douglas <brad@neruo.com>
*
* The low level operations for the various display memory organizations are
* now in separate source files.
*
* Currently the following organizations are supported:
*
* o afb Amiga bitplanes
* o cfb{2,4,8,16,24,32} Packed pixels
* o ilbm Amiga interleaved bitplanes
* o iplan2p[248] Atari interleaved bitplanes
* o mfb Monochrome
* o vga VGA characters/attributes
*
* To do:
*
* - Implement 16 plane mode (iplan2p16)

/* fbcon_XXX routines - interface used by the world
*
* This system is now divided into two levels because of complications
* caused by hardware scrolling. Top level functions:
*
* fbcon_bmove(), fbcon_clear(), fbcon_putc(), fbcon_clear_margins()
*
* handles y values in range [0, scr_height-1] that correspond to real
* screen positions. y_wrap shift means that first line of bitmap may be
* anywhere on this display. These functions convert lineoffsets to
* bitmap offsets and deal with the wrap-around case by splitting blits.
*
* fbcon_bmove_physical_8() -- These functions fast implementations
* fbcon_clear_physical_8() -- of original fbcon_XXX fns.
* fbcon_putc_physical_8() -- (font width != 8) may be added later
*
* WARNING:
*
* At the moment fbcon_putc() cannot blit across vertical wrap boundary
* Implies should only really hardware scroll in rows. Only reason for
* restriction is simplicity & efficiency at the moment.
