The Linux 31 * logo can be placed in the upper left corner and additional board 32 * information strings (that normaly goes to serial port) can be drawed. 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 delay 63 loop in VIDEO_TSTC_FCT (i8042) 64 CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate 65 CONFIG_CONSOLE_TIME - display time/date in upper right corner, 66 needs CONFIG_CMD_DATE and CONFIG_CONSOLE_CURSOR 67 CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner 68 CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo 69 CONFIG_CONSOLE_EXTRA_INFO - display additional board information strings 70 that normaly goes to serial port. This define 71 requires a board specific function: 72 video_drawstring (VIDEO_INFO_X, 73 VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 74 info); 75 that fills a info buffer at i=row. 76 s.a: board/eltec/bab7xx. 77 CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be initialised 78 as an output only device. The Keyboard driver 79 will not be set-up. This may be used, if you 80 have none or more than one Keyboard devices 81 (USB Keyboard, AT Keyboard). 82 83 CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last character. No 84 blinking is provided. Uses the macros CURSOR_SET 85 and CURSOR_OFF. 86 CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability of the 87 graphic chip. Uses the macro CURSOR_SET. 88 ATTENTION: If booting an OS, the display driver 89 must disable the hardware register of the graphic 90 chip. Otherwise a blinking field is displayed 91 */ 92 93 #include <common.h> 94 95 #include <malloc.h> 96 97 /*****************************************************************************/ 98 /* Console device defines with SMI graphic */ 99 /* Any other graphic must change this section */ 100 /*****************************************************************************/ 101 102 #ifdef CONFIG_VIDEO_SMI_LYNXEM 103 104 #define VIDEO_FB_LITTLE_ENDIAN 105 #define VIDEO_HW_RECTFILL 106 #define VIDEO_HW_BITBLT 107 #endif 108 109 /*****************************************************************************/ 110 /* Defines for the CT69000 driver */ 111 /*****************************************************************************/ 112 #ifdef CONFIG_VIDEO_CT69000 113 114 #define VIDEO_FB_LITTLE_ENDIAN 115 #define VIDEO_HW_RECTFILL 116 #define VIDEO_HW_BITBLT 117 #endif 118 119 /*****************************************************************************/ 120 /* Defines for the SED13806 driver */ 121 /*****************************************************************************/ 122 #ifdef CONFIG_VIDEO_SED13806 123 124 #ifndef CONFIG_TOTAL5200 125 #define VIDEO_FB_LITTLE_ENDIAN 126 #endif 127 #define VIDEO_HW_RECTFILL 128 #define VIDEO_HW_BITBLT 129 #endif 130 131 /*****************************************************************************/ 132 /* Defines for the SED13806 driver */ 133 /*****************************************************************************/ 134 #ifdef CONFIG_VIDEO_SM501 135 136 #ifdef CONFIG_HH405 137 #define VIDEO_FB_LITTLE_ENDIAN 138 #endif 139 #endif 140 141 /*****************************************************************************/ 142 /* Defines for the MB862xx driver */ 143 /*****************************************************************************/ 144 #ifdef CONFIG_VIDEO_MB862xx 145 146 #ifdef CONFIG_VIDEO_CORALP 147 #define VIDEO_FB_LITTLE_ENDIAN 148 #endif 149 #ifdef CONFIG_VIDEO_MB862xx_ACCEL 150 #define VIDEO_HW_RECTFILL 151 #define VIDEO_HW_BITBLT 152 #endif 153 #endif 154 155 /*****************************************************************************/ 156 /* Include video_fb.h after definitions of VIDEO_HW_RECTFILL etc */ 157 /*****************************************************************************/ 158 #include <video_fb.h> 159 160 /*****************************************************************************/ 161 /* some Macros */ 162 /*****************************************************************************/ 163 #define VIDEO_VISIBLE_COLS (pGD->winSizeX) 164 #define VIDEO_VISIBLE_ROWS (pGD->winSizeY) 165 #define VIDEO_PIXEL_SIZE (pGD->gdfBytesPP) 166 #define VIDEO_DATA_FORMAT (pGD->gdfIndex) 167 #define VIDEO_FB_ADRS (pGD->frameAdrs) 168 169 /*****************************************************************************/ 170 /* Console device defines with i8042 keyboard controller */ 171 /* Any other keyboard controller must change this section */ 172 /*****************************************************************************/ 173 174 #ifdef CONFIG_I8042_KBD 175 #include <i8042.h> 176 177 #define VIDEO_KBD_INIT_FCT i8042_kbd_init() 178 #define VIDEO_TSTC_FCT i8042_tstc 179 #define VIDEO_GETC_FCT i8042_getc 180 #endif 181 182 /*****************************************************************************/ 183 /* Console device */ 184 /*****************************************************************************/ 185 186 #include <version.h> 187 #include <linux/types.h> 188 #include <stdio_dev.h> 189 #include <video_font.h> 190 191 #if defined(CONFIG_CMD_DATE) 192 #include <rtc.h> 193 #endif 194 195 #if defined(CONFIG_CMD_BMP) || defined(CONFIG_SPLASH_SCREEN) 196 #include <watchdog.h> 197 #include <bmp_layout.h> 198 199 #ifdef CONFIG_SPLASH_SCREEN_ALIGN 200 #define BMP_ALIGN_CENTER 0x7FFF 201 #endif 202 203 #endif 204 205 /*****************************************************************************/ 206 /* Cursor definition: */ 207 /* CONFIG_CONSOLE_CURSOR: Uses a timer function (see drivers/input/i8042.c) */ 208 /* to let the cursor blink.
