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 * Use CONFIG_SPLASH_SCREEN_ALIGN with 71 * environment variable "splashpos" to place 72 * the logo on other position. In this case 73 * no CONSOLE_EXTRA_INFO is possible. 74 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo 75 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information 76 * strings that normaly goes to serial 77 * port. This define requires a board 78 * specific function: 79 * video_drawstring (VIDEO_INFO_X, 80 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 81 * info); 82 * that fills a info buffer at i=row. 83 * s.a: board/eltec/bab7xx. 84 * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be 85 * initialized as an output only device. 86 * The Keyboard driver will not be 87 * set-up. This may be used, if you have 88 * no or more than one Keyboard devices 89 * (USB Keyboard, AT Keyboard). 90 * 91 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last 92 * character. No blinking is provided. 93 * Uses the macros CURSOR_SET and 94 * CURSOR_OFF. 95 * 96 * CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability 97 * of the graphic chip. Uses the macro 98 * CURSOR_SET. ATTENTION: If booting an 99 * OS, the display driver must disable 100 * the hardware register of the graphic 101 * chip. Otherwise a blinking field is 102 * displayed. 103 */ 104 105 #include <common.h> 106 #include <version.h> 107 #include <malloc.h> 108 #include <linux/compiler.h> 109 110 /* 111 * Console device defines with SMI graphic 112 * Any other graphic must change this section 113 */ 114 115 #ifdef CONFIG_VIDEO_SMI_LYNXEM 116 117 #define VIDEO_FB_LITTLE_ENDIAN 118 #define VIDEO_HW_RECTFILL 119 #define VIDEO_HW_BITBLT 120 #endif 121 122 /* 123 * Defines for the CT69000 driver 124 */ 125 #ifdef CONFIG_VIDEO_CT69000 126 127 #define VIDEO_FB_LITTLE_ENDIAN 128 #define VIDEO_HW_RECTFILL 129 #define VIDEO_HW_BITBLT 130 #endif 131 132 /* 133 * Defines for the SED13806 driver 134 */ 135 #ifdef CONFIG_VIDEO_SED13806 136 137 #ifndef CONFIG_TOTAL5200 138 #define VIDEO_FB_LITTLE_ENDIAN 139 #endif 140 #define VIDEO_HW_RECTFILL 141 #define VIDEO_HW_BITBLT 142 #endif 143 144 /* 145 * Defines for the SED13806 driver 146 */ 147 #ifdef CONFIG_VIDEO_SM501 148 149 #ifdef CONFIG_HH405 150 #define VIDEO_FB_LITTLE_ENDIAN 151 #endif 152 #endif 153 154 #ifdef CONFIG_VIDEO_MXS 155 #define VIDEO_FB_16BPP_WORD_SWAP 156 #endif 157 158 /* 159 * Defines for the MB862xx driver 160 */ 161 #ifdef CONFIG_VIDEO_MB862xx 162 163 #ifdef CONFIG_VIDEO_CORALP 164 #define VIDEO_FB_LITTLE_ENDIAN 165 #endif 166 #ifdef CONFIG_VIDEO_MB862xx_ACCEL 167 #define VIDEO_HW_RECTFILL 168 #define VIDEO_HW_BITBLT 169 #endif 170 #endif 171 172 /* 173 * Defines for the i.MX31 driver (mx3fb.c) 174 */ 175 #if defined(CONFIG_VIDEO_MX3) || defined(CONFIG_VIDEO_IPUV3) 176 #define VIDEO_FB_16BPP_WORD_SWAP 177 #endif 178 179 /* 180 * Include video_fb.h after definitions of VIDEO_HW_RECTFILL etc. 181 */ 182 #include <video_fb.h> 183 184 #include <splash.h> 185 186 /* 187 * some Macros 188 */ 189 #define VIDEO_VISIBLE_COLS (pGD->winSizeX) 190 #define VIDEO_VISIBLE_ROWS (pGD->winSizeY) 191 #define VIDEO_PIXEL_SIZE (pGD->gdfBytesPP) 192 #define VIDEO_DATA_FORMAT (pGD->gdfIndex) 193 #define VIDEO_FB_ADRS (pGD->frameAdrs) 194 195 /* 196 * Console device defines with i8042 keyboard controller 197 * Any other keyboard controller must change this section 198 */ 199 200 #ifdef CONFIG_I8042_KBD 201 #include <i8042.h> 202 203 #define VIDEO_KBD_INIT_FCT i8042_kbd_init() 204 #define VIDEO_TSTC_FCT i8042_tstc 205 #define VIDEO_GETC_FCT i8042_getc 206 #endif 207 208 /* 209 * Console device 210 */ 211 212 #include <version.h> 213 #include <linux/types.h> 214 #include <stdio_dev.h> 215 #include <video_font.h> 216 #include <video_font_data.h> 217 218 #if defined(CONFIG_CMD_DATE) 219 #include <rtc.h> 220 #endif 221 222 #if defined(CONFIG_CMD_BMP) || defined(CONFIG_SPLASH_SCREEN) 223 #include <watchdog.h> 224 #include <bmp_layout.h> 225 #include <splash.h> 226 #endif 227 228 /* 229 * Cursor definition: 230 * CONFIG_CONSOLE_CURSOR: Uses a timer function (see drivers/input/i8042.c) 231 * to let the cursor blink.
