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 #include <linux/compiler.h> 105 106 /* 107 * Console device defines with SMI graphic 108 * Any other graphic must change this section 109 */ 110 111 #ifdef CONFIG_VIDEO_SMI_LYNXEM 112 113 #define VIDEO_FB_LITTLE_ENDIAN 114 #define VIDEO_HW_RECTFILL 115 #define VIDEO_HW_BITBLT 116 #endif 117 118 /* 119 * Defines for the CT69000 driver 120 */ 121 #ifdef CONFIG_VIDEO_CT69000 122 123 #define VIDEO_FB_LITTLE_ENDIAN 124 #define VIDEO_HW_RECTFILL 125 #define VIDEO_HW_BITBLT 126 #endif 127 128 /* 129 * Defines for the SED13806 driver 130 */ 131 #ifdef CONFIG_VIDEO_SED13806 132 133 #ifndef CONFIG_TOTAL5200 134 #define VIDEO_FB_LITTLE_ENDIAN 135 #endif 136 #define VIDEO_HW_RECTFILL 137 #define VIDEO_HW_BITBLT 138 #endif 139 140 /* 141 * Defines for the SED13806 driver 142 */ 143 #ifdef CONFIG_VIDEO_SM501 144 145 #ifdef CONFIG_HH405 146 #define VIDEO_FB_LITTLE_ENDIAN 147 #endif 148 #endif 149 150 /* 151 * Defines for the MB862xx driver 152 */ 153 #ifdef CONFIG_VIDEO_MB862xx 154 155 #ifdef CONFIG_VIDEO_CORALP 156 #define VIDEO_FB_LITTLE_ENDIAN 157 #endif 158 #ifdef CONFIG_VIDEO_MB862xx_ACCEL 159 #define VIDEO_HW_RECTFILL 160 #define VIDEO_HW_BITBLT 161 #endif 162 #endif 163 164 /* 165 * Defines for the i.MX31 driver (mx3fb.c) 166 */ 167 #if defined(CONFIG_VIDEO_MX3) || defined(CONFIG_VIDEO_MX5) 168 #define VIDEO_FB_16BPP_WORD_SWAP 169 #endif 170 171 /* 172 * Include video_fb.h after definitions of VIDEO_HW_RECTFILL etc. 173 */ 174 #include <video_fb.h> 175 176 /* 177 * some Macros 178 */ 179 #define VIDEO_VISIBLE_COLS (pGD->winSizeX) 180 #define VIDEO_VISIBLE_ROWS (pGD->winSizeY) 181 #define VIDEO_PIXEL_SIZE (pGD->gdfBytesPP) 182 #define VIDEO_DATA_FORMAT (pGD->gdfIndex) 183 #define VIDEO_FB_ADRS (pGD->frameAdrs) 184 185 /* 186 * Console device defines with i8042 keyboard controller 187 * Any other keyboard controller must change this section 188 */ 189 190 #ifdef CONFIG_I8042_KBD 191 #include <i8042.h> 192 193 #define VIDEO_KBD_INIT_FCT i8042_kbd_init() 194 #define VIDEO_TSTC_FCT i8042_tstc 195 #define VIDEO_GETC_FCT i8042_getc 196 #endif 197 198 /* 199 * Console device 200 */ 201 202 #include <version.h> 203 #include <linux/types.h> 204 #include <stdio_dev.h> 205 #include <video_font.h> 206 #include <video_font_data.h> 207 208 #if defined(CONFIG_CMD_DATE) 209 #include <rtc.h> 210 #endif 211 212 #if defined(CONFIG_CMD_BMP) || defined(CONFIG_SPLASH_SCREEN) 213 #include <watchdog.h> 214 #include <bmp_layout.h> 215 216 #ifdef CONFIG_SPLASH_SCREEN_ALIGN 217 #define BMP_ALIGN_CENTER 0x7FFF 218 #endif 219 220 #endif 221 222 /* 223 * Cursor definition: 224 * CONFIG_CONSOLE_CURSOR: Uses a timer function (see drivers/input/i8042.c) 225 * to let the cursor blink.
