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 the standard PC keyboard interface (i8042) 19 * for character input. Character output goes to a memory mapped video 20 * framebuffer with little or big-endian organisation. 21 * With environment setting 'console=serial' the console i/o can be 22 * forced to serial port. 23 * 24 * The driver uses graphic specific defines/parameters/functions: 25 * 26 * (for SMI LynxE graphic chip) 27 * 28 * CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810 29 * VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian 30 * VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill 31 * VIDEO_HW_BITBLT - graphic driver supports hardware bit blt 32 * 33 * Console Parameters are set by graphic drivers global struct: 34 * 35 * VIDEO_VISIBLE_COLS - x resolution 36 * VIDEO_VISIBLE_ROWS - y resolution 37 * VIDEO_PIXEL_SIZE - storage size in byte per pixel 38 * VIDEO_DATA_FORMAT - graphical data format GDF 39 * VIDEO_FB_ADRS - start of video memory 40 * 41 * CONFIG_I8042_KBD - AT Keyboard driver for i8042 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_CONSOLE_CURSOR - on/off drawing cursor is done with 47 * delay loop in VIDEO_TSTC_FCT (i8042) 48 * 49 * CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate 50 * CONFIG_CONSOLE_TIME - display time/date in upper right 51 * corner, needs CONFIG_CMD_DATE and 52 * CONFIG_CONSOLE_CURSOR 53 * CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner. 54 * Use CONFIG_SPLASH_SCREEN_ALIGN with 55 * environment variable "splashpos" to place 56 * the logo on other position. In this case 57 * no CONSOLE_EXTRA_INFO is possible. 58 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo 59 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information 60 * strings that normaly goes to serial 61 * port. This define requires a board 62 * specific function: 63 * video_drawstring (VIDEO_INFO_X, 64 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 65 * info); 66 * that fills a info buffer at i=row. 67 * s.a: board/eltec/bab7xx. 68 * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be 69 * initialized as an output only device. 70 * The Keyboard driver will not be 71 * set-up. This may be used, if you have 72 * no or more than one Keyboard devices 73 * (USB Keyboard, AT Keyboard). 74 * 75 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last 76 * character. No blinking is provided. 77 * Uses the macros CURSOR_SET and 78 * CURSOR_OFF. 79 * 80 * CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability 81 * of the graphic chip. Uses the macro 82 * CURSOR_SET. ATTENTION: If booting an 83 * OS, the display driver must disable 84 * the hardware register of the graphic 85 * chip. Otherwise a blinking field is 86 * displayed. 87 */ 88 89 #include <common.h> 90 #include <version.h> 91 #include <malloc.h> 92 #include <linux/compiler.h> 93 94 /* 95 * Console device defines with SMI graphic 96 * Any other graphic must change this section 97 */ 98 99 #ifdef CONFIG_VIDEO_SMI_LYNXEM 100 101 #define VIDEO_FB_LITTLE_ENDIAN 102 #define VIDEO_HW_RECTFILL 103 #define VIDEO_HW_BITBLT 104 #endif 105 106 /* 107 * Defines for the CT69000 driver 108 */ 109 #ifdef CONFIG_VIDEO_CT69000 110 111 #define VIDEO_FB_LITTLE_ENDIAN 112 #define VIDEO_HW_RECTFILL 113 #define VIDEO_HW_BITBLT 114 #endif 115 116 /* 117 * Defines for the SED13806 driver 118 */ 119 #ifdef CONFIG_VIDEO_SED13806 120 121 #ifndef CONFIG_TOTAL5200 122 #define VIDEO_FB_LITTLE_ENDIAN 123 #endif 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_SM501 132 133 #ifdef CONFIG_HH405 134 #define VIDEO_FB_LITTLE_ENDIAN 135 #endif 136 #endif 137 138 #ifdef CONFIG_VIDEO_MXS 139 #define VIDEO_FB_16BPP_WORD_SWAP 140 #endif 141 142 /* 143 * Defines for the MB862xx driver 144 */ 145 #ifdef CONFIG_VIDEO_MB862xx 146 147 #ifdef CONFIG_VIDEO_CORALP 148 #define VIDEO_FB_LITTLE_ENDIAN 149 #endif 150 #ifdef CONFIG_VIDEO_MB862xx_ACCEL 151 #define VIDEO_HW_RECTFILL 152 #define VIDEO_HW_BITBLT 153 #endif 154 #endif 155 156 /* 157 * Defines for the i.MX31 driver (mx3fb.c) 158 */ 159 #if defined(CONFIG_VIDEO_MX3) || defined(CONFIG_VIDEO_IPUV3) 160 #define VIDEO_FB_16BPP_WORD_SWAP 161 #endif 162 163 /* 164 * Include video_fb.h after definitions of VIDEO_HW_RECTFILL etc. 165 */ 166 #include <video_fb.h> 167 168 #include <splash.h> 169 170 /* 171 * some Macros 172 */ 173 #define VIDEO_VISIBLE_COLS (pGD->winSizeX) 174 #define VIDEO_VISIBLE_ROWS (pGD->winSizeY) 175 #define VIDEO_PIXEL_SIZE (pGD->gdfBytesPP) 176 #define VIDEO_DATA_FORMAT (pGD->gdfIndex) 177 #define VIDEO_FB_ADRS (pGD->frameAdrs) 178 179 /* 180 * Console device defines with i8042 keyboard controller 181 * Any other keyboard controller must change this section 182 */ 183 184 #ifdef CONFIG_I8042_KBD 185 #include <i8042.h> 186 187 #define VIDEO_KBD_INIT_FCT i8042_kbd_init() 188 #define VIDEO_TSTC_FCT i8042_tstc 189 #define VIDEO_GETC_FCT i8042_getc 190 #endif 191 192 /* 193 * Console device 194 */ 195 196 #include <version.h> 197 #include <linux/types.h> 198 #include <stdio_dev.h> 199 #include <video_font.h> 200 #include <video_font_data.h> 201 202 #if defined(CONFIG_CMD_DATE) 203 #include <rtc.h> 204 #endif 205 206 #if defined(CONFIG_CMD_BMP) || defined(CONFIG_SPLASH_SCREEN) 207 #include <watchdog.h> 208 #include <bmp_layout.h> 209 #include <splash.h> 210 #endif 211 212 /* 213 * Cursor definition: 214 * CONFIG_CONSOLE_CURSOR: Uses a timer function (see drivers/input/i8042.c) 215 * to let the cursor blink.
