The Linux 31 * logo can be placed in the upper left corner and additional board 32 * information strings (that normally goes to serial port) can be drawn. 33 * 34 * The console driver can use the standard PC keyboard interface (i8042) 35 * for character input. Character output goes to a memory mapped video 36 * framebuffer with little or big-endian organisation. 37 * With environment setting 'console=serial' the console i/o can be 38 * forced to serial port. 39 * 40 * The driver uses graphic specific defines/parameters/functions: 41 * 42 * (for SMI LynxE graphic chip) 43 * 44 * CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810 45 * VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian 46 * VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill 47 * VIDEO_HW_BITBLT - graphic driver supports hardware bit blt 48 * 49 * Console Parameters are set by graphic drivers global struct: 50 * 51 * VIDEO_VISIBLE_COLS - x resolution 52 * VIDEO_VISIBLE_ROWS - y resolution 53 * VIDEO_PIXEL_SIZE - storage size in byte per pixel 54 * VIDEO_DATA_FORMAT - graphical data format GDF 55 * VIDEO_FB_ADRS - start of video memory 56 * 57 * CONFIG_I8042_KBD - AT Keyboard driver for i8042 58 * VIDEO_KBD_INIT_FCT - init function for keyboard 59 * VIDEO_TSTC_FCT - keyboard_tstc function 60 * VIDEO_GETC_FCT - keyboard_getc function 61 * 62 * CONFIG_CONSOLE_CURSOR - on/off drawing cursor is done with 63 * delay loop in VIDEO_TSTC_FCT (i8042) 64 * 65 * CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate 66 * CONFIG_CONSOLE_TIME - display time/date in upper right 67 * corner, needs CONFIG_CMD_DATE and 68 * CONFIG_CONSOLE_CURSOR 69 * CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner 70 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo 71 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information 72 * strings that normaly goes to serial 73 * port. This define requires a board 74 * specific function: 75 * video_drawstring (VIDEO_INFO_X, 76 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 77 * info); 78 * that fills a info buffer at i=row. 79 * s.a: board/eltec/bab7xx. 80 * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be 81 * initialized as an output only device. 82 * The Keyboard driver will not be 83 * set-up. This may be used, if you have 84 * no or more than one Keyboard devices 85 * (USB Keyboard, AT Keyboard). 86 * 87 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last 88 * character. No blinking is provided. 89 * Uses the macros CURSOR_SET and 90 * CURSOR_OFF. 91 * 92 * CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability 93 * of the graphic chip. Uses the macro 94 * CURSOR_SET. ATTENTION: If booting an 95 * OS, the display driver must disable 96 * the hardware register of the graphic 97 * chip. Otherwise a blinking field is 98 * displayed. 99 */ 100 101 #include <common.h> 102 #include <version.h> 103 #include <malloc.h> 104 105 /* 106 * Console device defines with SMI graphic 107 * Any other graphic must change this section 108 */ 109 110 #ifdef CONFIG_VIDEO_SMI_LYNXEM 111 112 #define VIDEO_FB_LITTLE_ENDIAN 113 #define VIDEO_HW_RECTFILL 114 #define VIDEO_HW_BITBLT 115 #endif 116 117 /* 118 * Defines for the CT69000 driver 119 */ 120 #ifdef CONFIG_VIDEO_CT69000 121 122 #define VIDEO_FB_LITTLE_ENDIAN 123 #define VIDEO_HW_RECTFILL 124 #define VIDEO_HW_BITBLT 125 #endif 126 127 /* 128 * Defines for the SED13806 driver 129 */ 130 #ifdef CONFIG_VIDEO_SED13806 131 132 #ifndef CONFIG_TOTAL5200 133 #define VIDEO_FB_LITTLE_ENDIAN 134 #endif 135 #define VIDEO_HW_RECTFILL 136 #define VIDEO_HW_BITBLT 137 #endif 138 139 /* 140 * Defines for the SED13806 driver 141 */ 142 #ifdef CONFIG_VIDEO_SM501 143 144 #ifdef CONFIG_HH405 145 #define VIDEO_FB_LITTLE_ENDIAN 146 #endif 147 #endif 148 149 /* 150 * Defines for the MB862xx driver 151 */ 152 #ifdef CONFIG_VIDEO_MB862xx 153 154 #ifdef CONFIG_VIDEO_CORALP 155 #define VIDEO_FB_LITTLE_ENDIAN 156 #endif 157 #ifdef CONFIG_VIDEO_MB862xx_ACCEL 158 #define VIDEO_HW_RECTFILL 159 #define VIDEO_HW_BITBLT 160 #endif 161 #endif 162 163 /* 164 * Include video_fb.h after definitions of VIDEO_HW_RECTFILL etc. 165 */ 166 #include <video_fb.h> 167 168 /* 169 * some Macros 170 */ 171 #define VIDEO_VISIBLE_COLS (pGD->winSizeX) 172 #define VIDEO_VISIBLE_ROWS (pGD->winSizeY) 173 #define VIDEO_PIXEL_SIZE (pGD->gdfBytesPP) 174 #define VIDEO_DATA_FORMAT (pGD->gdfIndex) 175 #define VIDEO_FB_ADRS (pGD->frameAdrs) 176 177 /* 178 * Console device defines with i8042 keyboard controller 179 * Any other keyboard controller must change this section 180 */ 181 182 #ifdef CONFIG_I8042_KBD 183 #include <i8042.h> 184 185 #define VIDEO_KBD_INIT_FCT i8042_kbd_init() 186 #define VIDEO_TSTC_FCT i8042_tstc 187 #define VIDEO_GETC_FCT i8042_getc 188 #endif 189 190 /* 191 * Console device 192 */ 193 194 #include <version.h> 195 #include <linux/types.h> 196 #include <stdio_dev.h> 197 #include <video_font.h> 198 199 #if defined(CONFIG_CMD_DATE) 200 #include <rtc.h> 201 #endif 202 203 #if defined(CONFIG_CMD_BMP) || defined(CONFIG_SPLASH_SCREEN) 204 #include <watchdog.h> 205 #include <bmp_layout.h> 206 207 #ifdef CONFIG_SPLASH_SCREEN_ALIGN 208 #define BMP_ALIGN_CENTER 0x7FFF 209 #endif 210 211 #endif 212 213 /* 214 * Cursor definition: 215 * CONFIG_CONSOLE_CURSOR: Uses a timer function (see drivers/input/i8042.c) 216 * to let the cursor blink.
