The Linux 15 * logo can be placed in the upper left corner and additional board 16 * information strings (that normally goes to serial port) can be drawn. 17 * 18 * The console driver can use a keyboard interface for character input 19 * but this is deprecated. Only rk51 uses it. 20 * 21 * Character output goes to a memory-mapped video 22 * framebuffer with little or big-endian organisation. 23 * With environment setting 'console=serial' the console i/o can be 24 * forced to serial port. 25 * 26 * The driver uses graphic specific defines/parameters/functions: 27 * 28 * (for SMI LynxE graphic chip) 29 * 30 * VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian 31 * VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill 32 * VIDEO_HW_BITBLT - graphic driver supports hardware bit blt 33 * 34 * Console Parameters are set by graphic drivers global struct: 35 * 36 * VIDEO_VISIBLE_COLS - x resolution 37 * VIDEO_VISIBLE_ROWS - y resolution 38 * VIDEO_PIXEL_SIZE - storage size in byte per pixel 39 * VIDEO_DATA_FORMAT - graphical data format GDF 40 * VIDEO_FB_ADRS - start of video memory 41 * 42 * VIDEO_KBD_INIT_FCT - init function for keyboard 43 * VIDEO_TSTC_FCT - keyboard_tstc function 44 * VIDEO_GETC_FCT - keyboard_getc function 45 * 46 * CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner. 47 * Use CONFIG_SPLASH_SCREEN_ALIGN with 48 * environment variable "splashpos" to place 49 * the logo on other position. In this case 50 * no CONSOLE_EXTRA_INFO is possible. 51 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo 52 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information 53 * strings that normaly goes to serial 54 * port. This define requires a board 55 * specific function: 56 * video_drawstring (VIDEO_INFO_X, 57 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 58 * info); 59 * that fills a info buffer at i=row. 60 * s.a: board/eltec/bab7xx. 61 * 62 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last 63 * character.
