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 a keyboard interface for character input 19 * but this is deprecated. Only rk51 uses it. 20 * 21 * Character output goes to a memory-mapped video 22 * framebuffer with little or big-endian organisation. 23 * With environment setting 'console=serial' the console i/o can be 24 * forced to serial port. 25 * 26 * The driver uses graphic specific defines/parameters/functions: 27 * 28 * (for SMI LynxE graphic chip) 29 * 30 * VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian 31 * VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill 32 * VIDEO_HW_BITBLT - graphic driver supports hardware bit blt 33 * 34 * Console Parameters are set by graphic drivers global struct: 35 * 36 * VIDEO_VISIBLE_COLS - x resolution 37 * VIDEO_VISIBLE_ROWS - y resolution 38 * VIDEO_PIXEL_SIZE - storage size in byte per pixel 39 * VIDEO_DATA_FORMAT - graphical data format GDF 40 * VIDEO_FB_ADRS - start of video memory 41 * 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_VIDEO_LOGO - display Linux Logo in upper left corner. 47 * Use CONFIG_SPLASH_SCREEN_ALIGN with 48 * environment variable "splashpos" to place 49 * the logo on other position. In this case 50 * no CONSOLE_EXTRA_INFO is possible. 51 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo 52 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information 53 * strings that normaly goes to serial 54 * port. This define requires a board 55 * specific function: 56 * video_drawstring (VIDEO_INFO_X, 57 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, 58 * info); 59 * that fills a info buffer at i=row. 60 * s.a: board/eltec/bab7xx. 61 * CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be 62 * initialized as an output only device. 63 * The Keyboard driver will not be 64 * set-up. This may be used, if you have 65 * no or more than one Keyboard devices 66 * (USB Keyboard, AT Keyboard). 67 * 68 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last 69 * character. No blinking is provided. 70 * Uses the macros CURSOR_SET and 71 * CURSOR_OFF. 72 * 73 * CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability 74 * of the graphic chip. Uses the macro 75 * CURSOR_SET. ATTENTION: If booting an 76 * OS, the display driver must disable 77 * the hardware register of the graphic 78 * chip. Otherwise a blinking field is 79 * displayed. 80 */ 81 82 #include <common.h> 83 #include <fdtdec.h> 84 #include <version.h> 85 #include <malloc.h> 86 #include <linux/compiler.h> 87 88 /* 89 * Defines for the CT69000 driver 90 */ 91 #ifdef CONFIG_VIDEO_CT69000 92 93 #define VIDEO_FB_LITTLE_ENDIAN 94 #define VIDEO_HW_RECTFILL 95 #define VIDEO_HW_BITBLT 96 #endif 97 98 /* 99 * Defines for the SED13806 driver 100 */ 101 #ifdef CONFIG_VIDEO_SED13806 102 #define VIDEO_FB_LITTLE_ENDIAN 103 #define VIDEO_HW_RECTFILL 104 #define VIDEO_HW_BITBLT 105 #endif 106 107 #if defined(CONFIG_VIDEO_MXS) || defined(CONFIG_VIDEO_S3C) 108 #define VIDEO_FB_16BPP_WORD_SWAP 109 #endif 110 111 /* 112 * Defines for the MB862xx driver 113 */ 114 #ifdef CONFIG_VIDEO_MB862xx 115 116 #ifdef CONFIG_VIDEO_CORALP 117 #define VIDEO_FB_LITTLE_ENDIAN 118 #endif 119 #ifdef CONFIG_VIDEO_MB862xx_ACCEL 120 #define VIDEO_HW_RECTFILL 121 #define VIDEO_HW_BITBLT 122 #endif 123 #endif 124 125 /* 126 * Defines for the i.MX31 driver (mx3fb.c) 127 */ 128 #if defined(CONFIG_VIDEO_MX3) || defined(CONFIG_VIDEO_IPUV3) 129 #define VIDEO_FB_16BPP_WORD_SWAP 130 #endif 131 132 /* 133 * Include video_fb.h after definitions of VIDEO_HW_RECTFILL etc. 134 */ 135 #include <video_fb.h> 136 137 #include <splash.h> 138 139 /* 140 * some Macros 141 */ 142 #define VIDEO_VISIBLE_COLS (pGD->winSizeX) 143 #define VIDEO_VISIBLE_ROWS (pGD->winSizeY) 144 #define VIDEO_PIXEL_SIZE (pGD->gdfBytesPP) 145 #define VIDEO_DATA_FORMAT (pGD->gdfIndex) 146 #define VIDEO_FB_ADRS (pGD->frameAdrs) 147 148 /* 149 * Console device 150 */ 151 152 #include <version.h> 153 #include <linux/types.h> 154 #include <stdio_dev.h> 155 #include <video_font.h> 156 157 #if defined(CONFIG_CMD_DATE) 158 #include <rtc.h> 159 #endif 160 161 #if defined(CONFIG_CMD_BMP) || defined(CONFIG_SPLASH_SCREEN) 162 #include <watchdog.h> 163 #include <bmp_layout.h> 164 #include <splash.h> 165 #endif 166 167 /* 168 * Cursor definition: 169 * CONFIG_VIDEO_SW_CURSOR: Draws a cursor after the last character.
